I have finally decided to document my Placement journey. May be for the use of aspirants but atleast for my record I will also try to list out the questions asked and the type of apti paper. I will be writing about those companies for which I qualified to the interview round.

The first company in the list is DirectI. Very few in the college knew that such a company existed I knew about the company as it had sponsored GIDS-2008. They were coming to the campus for the first time and had uploaded huge information on the site regarding their selection procedure and interviews. Their recruitment site looked really resourceful and they were looking for people with really good coding and technical skills. I still remember their PPT which went on for more than an hour and half and i had to listen to the whole presentation standing and moreover is was terribly sick that day- running nose, fever . Their selection process was a bit different- No apti, instead an online programming test on their coding platform- CodeChef which they were badly promoting , then 2 rounds at the campus and some 9-10 rounds in their Mumbai Head office . Luckily they had to postpone the Coding test because by the time they completed their presentation it was 7PM and the Computer Center would be open only till 8PM. So they decided to come some other time for the coding test. I was happy that atleast i got sometime to recover and get well before the test.

One fine day they informed us that the test will be in the afternoon. I was aiming to clear the coding round and wasnt concerned about the interviews. The coding test was not tat difficult either. We were given 2 questions to solve and some 20 of them did one of the two, I was one among them and no one was able to crack both the problems. I was one among the some 11 or 12 ppl shortlisted for interviews . And the fun part was that few had telephonic interviews and some 2 or 3 had face2face. I had a telephonic interview a long one- for around 2 hours and it was not good They asked me few algorithm based questions though i answered them but the solutions were not efficient . Then they asked me few technology based questions and as i had not prepared for the interview i couldn’t answer them effectively. After everyone was done with their interviews we were told that selected few would have a HR round and then few those who clear HR will be flown to Mumbai for their final interviews. For me the result was obvious- Not cleared the Tech interview One of my friend cleared the tech interview but in the next round they asked him questions regarding his projects and technologies used in the projects which he wasn’t able to answer effectively. Finally only 2 ppl from comps were selected for the grueling rounds at Mumbai. And the result was- No one was selected from NITK

The questions they asked me were-

1. Write a function which takes 2 arrays- One array is the source array and the other array is the array of indices and delete all those elements present at the indices of the source array taking the indices from the second array.

2. There’s a huge data of stock prices for a given duration. Find out on which day the person if he sold his shares would get the maximum loss.

3. Then there was a question on finding the non repeating number in a array of repeating numbers.

4. HTTP is stateless protocol- How does it manage the state- Explain the cookie mechanism

5. Difference between Unique and Primary key

6. Different indexes in database

The company works on cutting edge technologies like RoR, Python, PHP, Java, Web Services, REST and so on. Its a great place for ppl who like to try out new technologies. They have a real good work place with a saloon, gym, cafeteria among others. And they were offering 6-12 lacs of base salary with added benefits

I visited LBS College of Engineering, Kasaragod for a workshop organised by thier collegeOSUM Club. This was my first workshop outside NITK. They had suspended the classes for the afternoon so that most of them could attend the workshop. And its really great that the college is supporting them for the OSUM club as college’s support is of prime importance for the growth of the club.

They had booked the seminar hall from 1:30 till 4:00. It takes about 2 and half hours to travel from my college to Kasaragod. I was accompanied by my friend Manjunath. We left at 10:00 and reached Kasargod by 12:30 in the afternoon. We were received by Allan and his group members. They took us in their car for lunch and then from there we were driven to their college. I ate as much less as possible as I had to feel comformtable while giving the talk. Their college was on top of a small hill. The seminar hall was full by the time we reached the venue and we were in time unlike other speakers who most of the time reach the venue late. The seminar hall was packed and i guess some 150+ students attended the workshop.

We were introduced as the chief guests by one of their club members. The talk was also attend by their faculty co-ordinator. I had prepared on a higher concepts in Java- Strings, File I/O, Serialization, Multithreading, Graphics, Event Handling, Swing. I gave a brief overview of each of them and also wrote some simple programs using the Netbeans IDE. I extensively used the white board to explain different concepts. I gave them a brief overview of OOPS concepts as they were familiar with OOPS, i did not spend much time there. Also I had few goodies to give away for which I asked questions during my presentation. I felt the auidence was shy to answer may be because they were not familiar with the speaker I also carried few Netbeans 6.5 discs and OpenSolaris discs to distribute to the club members. This presentation was totally unlike my usual presentation. This time I was slow, interacting with the audience, cracking PJs between .

The OSUM Club had made perfect arrangements and the event went on really well. This was their first OSUM club event and there were a lot of expectations from me and I feel i did my job to the best possible extent. Hope this event will attract more students to be a part of the club.

Looking forward to visiting more colleges for presentations

Great Indian Developer Summit- 2009, Day-4. GIDS.Workshops:

DSL workshop by Venkat

This was the last day of the Great Indian Developer Summit-2009. There were 15 workshops running in parallel at 4 different halls. Workshops covered areas like JRuby, DSLs, Silverlight, Oslo, .Net, Hibernate, Adone Flash platform, COBOL among others. The first workshop I attended was “Developing external DSLs in Java” and was taken by Venkat Subramaniam who is regarded as the languages geek. He spoke about the need for Domain Specific Languages(DSL), different types of DSLs which include Internal DSL and External DSL. He told that internal DSLs can be created by using languages like Groovy, Ruby among others and External DSLs can be created using languages with higher parsing abilities like Java, C++, C#. Internal DSLs are also called as embedded DSL. He aslo threw some light on EasyB which is basically a behavior oriented design tool. He spoke at lenght on how to use Java to create external DSL using xText and Eclipse. He later gave a demo on using xText and created a game DSL. Sadly i couldn’t work it out on my comp as I did not have xText plugin installed in Eclipse.

Ola Bini and JRuby

JRuby Duke

The second workshop was “Introduction to JRuby” delivered by Ola Bini, who is one of the core developers of JRuby. He started with speaking about Ruby and JRuby features which was a repitition for me as i had attended his JRuby talk the other day. As he went ahead with his talk, I was busy configuring my Linux for running JRuby applications. Once he started writing some code i followed the same and got some taste of Ruby and JRuby. As the session progressed he went into much higher aspects of JRuby and finally spent some time explaining Ruby on Rails. RoR was the reason why Ruby developed interest which wasn’t there before though Ruby was much older than Java. Using RoR was similar to that of using Grails so there wasn’t much difficulty in getting the general idea but the Ruby related aspects were tough to digest. But i really appreciate and admire the languages Groovy and Ruby for they have added Elegance to the programming which was earlier very verbose thanks to Java . Though I really like the way Java is but once i was introduced to Groovy and Ruby, Java seemed like C to me.

Jim Webber in action

By the end of second workshop i was exhausted and rushed towards the dinning area for the last Lunch of GIDS-2009. As usual the lunch was really good with variety of dishes prepared for the developers to choose from which is analogous to the numerous technologies available. The third workshop was on “Web and Web based services and its integration” which by Jim Webber. Jim Webber is Director of ThoughtWorks and is the guru of web and web services. He spoke at length about Web, Web Characteristics, RESTful Web among other things. I was really tired and after a heavy lunch i couldn’t concentrate during this session, so i walked off and spent some time waiting near the registration desk to collect the summit T-Shirt. There was a developer awards function hosted by Cyrus Broacha  and i was eager to attend this function but i was really sick by the end of the day and had no courage to sit for another hour.

ThoughtWorkers under lens

GIDS-2008 and GIDS-2009 have been great learning experiences for me. Listening to best speakers from around the world and there were ocassions when the creators of the technology spoke about their creation. Its feels really great to listen to the creators themselves. The only thing i would want to change in the Great Indian Developer Summit is that they should be introducing some concesison for the student community because that is the heart of action. Though we students may not be experienced with new technologies but surely after listening to such great speakers will instill the desire to learn. GIDS is really a great initiative from Saltmarch media and I am looking forward to attending GIDS-2010 [This was the same thing i had written in my blog about the last edition ].

I was facing a problem while clearing the Trash in Ubuntu. I wasn’t able to delete certaion folder and i got the message stating “Access Denied”. So i was wondering that there should be some way to do it from the command prompt using sudo and some command. I did a google for the requirement and found the following shell snippet:

rm -rf ~/.local/share/Trash/

Ola Bina during JRuby talk

I started off pretty late for my Day-2 (summit’s Day-3) at the summit, courtesy- extended sleeping But I somehow managed to not miss much of the first session. The first session I attended today was “Introduction to JRuby” which was delivered by Ola Bini. He spoke about Ruby and its features like Blocks, Modules, Mixins among others. He then spoke about JRuby and how it eliminates the pain of using Java and leverages on the ease of Ruby. JRuby is basically Ruby running on JVM. This was developed keeping in mind the old legacy JavaEE based applications.

Venkat during Know u'r Java

Second session was “Know your Java?” delivered by my favorite speaker Venkat Submramaniam. He is a great speaker and i am sure one can continue to listen to him for long hours with out sleeping and getting bored. He did not bore us with the different Gotchas in Java but in turn asked the audience to choose the topic which included “string”, “Static”,”Inheritance”, “Math”, “Basic” and the questions were for 1000, 500 and 100 points. Each one had to choose one question and if he/she would answer it correctly would get the points alloted to that particular question. And he took the questions to explain the concept behind it which i feel is a really innovative way for such kind of topics. I am sure that he had written an application to help him out with this. There were few ppl who scored 1000 and they got the copies of books authored by him. Even last year in GIDS-2008 he gave away his .NET Gotchas book, but for this year’s event he had 4 books on Scala, Groovy, Agile Development and .NET to give away.

McClanahan during RESTful talk

The third session was on “RESTful approach” to developing applications which was devlivered by Craig McClanahan who was incidentally from Sun Microsystems and i was happy to see someone from Sun and was happy to see someone use NetBeans He spoke at length about REST and its different aspects like URI, Actions, Resources and so on. It was a verbose talk with out any code demo but there were 2 demos later in the day one on REST applications using JAX-RS and another using RoR. But the talk was really resourceful and McClanahan is the creator of Apache Struts!!!!

McClanahan during JAX-RS talk

The fourth session for the day was on “Developing RESTful applications using JAX-RS” which was again delivered by McClanahan. But he took a lot of time to summarise what he spoke in the previous session and when he was about to demo the application NetBeans crashed But he spoke about using Jersey which is the reference implementation of JAX-RS for creating RESTful applications. He told that resources were represented using POJOs and annotations were used to indicate which method to be called for which link- in other words using annotations to map the URI’s and Resource class and methods.

Venkat in action

The fifth session for the day was “Programming Groovy” again by Venkat Subramaniam. This was a really superb session and haviing been read thru his Programming Groovy book this session was more like a revision for me. He covered all the major concepts in Groovy and the best part of his session was that it was Powerpoint free. He explained all the concepts by writing code snippets. We were starlted to see the simplicity of Groovy and most of the audience had lots of doubts about the language and many of them missed their team to flock around Venkat to get their doubts cleared.

The sixth session was on SOA delivered by Jim Webbers. The speaker was a great actor and his presentation was lively and the audience were laughing thourgh out his presentation. Even i was laughing but i dont know the reason why i was laughing because i wasn’t listening to his talk but am writing this blog post .

My Day-2 (Day-3 of the Summit) at Great Indian Developer Summit-2009 was really interesting and i learnt a lot of new concepts, listened to really lively talks. I feel Great Indian Developer Summit-2009 is the best i have attended so far. Am seriously looking forward to attend Great Indian Developer Summit-2010. Meanwhile i have GIDS.Workshops to attend tomorrow. I will surely be attending Venkat’s workshop, then workshop on JRuby and the thirs i havent yet finalised

Read My Day-1 experiences at The Great Indian Developer Summit-2009 here.

I had attended the Great Indian Developer Summit 2008 which was held from May 19-25. I got a pass using which i attended Bleeding edge .NET and RichWeb though i had very very less experience on .NET. It was truly an amazing experience. And now here I am in Great Indian Developer Summit 2009. But this time i had to fund the expenses myself. I chose to attend RichWeb, Daring java and the Workshop sessions. Unlike last year each technology was covered only for a day and also the cost of registration decreased. The day’s proceeding were to start at 10:00 which included the registration, Welcome key note among others. Incidentally it happened to be poll time for B’loreans and after i finished my mandatory work of voting i rushed to the Auditorium in IISc where the summit was to be held.

The first session was on Enterprise 2.0 taken by Rajesh Ramachandran. From the word go I was sleepy and fought hard to keep my eyes open. All these Enterprise stuff is beyond my capablities He gave an insight on Web 2.0 and then quicikly went to finer aspects of Enterprise 2.0(E2O). He spoke about features of Enterprise 2.0, challenges and solutions and the Key drivers of Enterprise 2.0

The second session was my Fav. It was about Grails- which i believe is a really good framework to work on. This was devliered by Venkat Subramaniam, who is a really good speaker. What I like about Venkat’s talk is that there less of presentation and more of demo/coding. He quickly built a web application using grails framework, spoke about the features of the framework and there were many questions which he tackled tactfully.

Venkat's Grails Talk

By this I was tired and really hungry. The lunch was arranged at the venue. The lunch was outsourced to The Chancery and was good. After the lunch I went around the stalls, getting the Summit passport stamped by various stalls. It feels so bad that many go to the stall just to get their passports stamped and not listen to what they have to say. I answered a quiz at IBM stall and never thought that I would be lucky to win a IBM Developer Works bag and Parker pen. I still cant believe that i have won something

The third session was on different ways of debugging AJAX and again delivered by Venkat. It was really interesting talk where the speaker spoke about different debugging tools and techniques for debugging AJAX applications. During the talk he even distributed toffees to those who would just speak to

him and the person with most toffees got a gift from him. After this there was a key note address on Sony Ericsson’s developer world which i missed. There was a small tea break and this was followed by a session on Developing Rich application using Adobe Flash platform. There were 2 speakers and they spoke about the need for Rich applications and how Adobe Flash platform helps us to do it. They spoke about building SaaS applications and how the application can be used by different users.  Also they spoke about using Flex to access Java Objects and use flex with the server side languages with stress on MVC architecture.

Looking forward to tomorrow’s Java sessions and Groovy session by Venkat in particular.

IPL is back after a year! One year has passed so quickly, the Rajasthan Royals final match is still fresh in my mind This time IPL is being held out of India- Indian Premium League in South Africa Its was a day of upsets everywhere, a day of upset for me either- tough SE Exam paper The Inaugural match between Mumbai Indians(MI) and Chennai Super Kings(CSK) was at some point interesting but then MI comfortably won the match (looks comfortable for ppl watchin on TV, may not be for the players ) The main take aways from that match was- Tendulkar continuing his New Zealand form started off IPL in stlye with a 50 , Nayar smashed 3 sixes in Flintoff’s over (hope he sleeps peacefully tonight and those sixes don’t haunt him ). Malinga fierce with the ball- he is fiercefull without the ball either. And and any other key MI performances- I cant recall. Coming to CSK they had very little to cheer about- Gony took few wickets, Dhoni hit few runs ( Gony and Dhoni are so rhyming), so did Hayden. In the end wat matters is the winner and its MI (not Mission Impossible )

The second match- Bangalore Royal Challengers(B’lore RC) Vs Rajasthan Royals(RR). This match was played in the filled to capacity ground situated on Earth. I had taken for granted the RR(not Reading Room) would not win (everyone would have read it as would win) the reason being B’lore RC had like of Ryder, Taylor, Kevin (the other part of the name is too long), Dravid (order for listing is the batting order) and so on … B’lore RC had a great start- Ryder and Taylor falling cheaply, sorry very cheaply playing some stupid shots. Unlike 10Dulkar they couldn’t continue their good performances in New Zealand. Then Dravid resurrected the innings with a solid, rock solid, wall solid performance. Was he supported by Kevin?- No. I dont know wat Kevin was doing on the pitch- Was he dancing? I dont think he was batting . With a modest total- 133 to chase i thought RR would win but then there was a different story altogether. One by one RR batsmen fell initially to Praveen Kumar, Ryder (not fell in love, they got out) then finally to Kumble. Actually Kumble accounted for 50% of RR batsmen (i think he will be skipping his dinner). All these led to RR getting bowled out for 58- wow only 58.

Now its time for some Chak De India scenes in the RR dressing room given by Shilpa Shetty. Mallya will be happy- still not happiest because B’lore RC has a long way to go. Wat will Mallya be doing for B’lore RCs? Full time belting Ryder and Taylor, praising Dravid, Kumble, Praveen. Party time in B’lore RC dressing room, sponsored by UB Group

I had spent a lot of time setting the $PATH on my Ubuntu but i forgot to document the procedure. So when my friend asked me, i wasn’t able to help him out. So this time i asked him to tell the solution so that i could note it down. The best place would be my blog.

JAVA_HOME=/usr/lib/jvm/java
export JAVA_HOME
PATH=$PATH:$JAVA_HOME/bin
