How I started and got admission for MS in IIT Madras: Candidate experience

Hey GUYS, Ankit Here.  this is all about my experience to enroll for MS in IIT Madras. How I started and got admission:

I was preparing for the gate 2013 because I thought that gate 2012 score was not enough as I didn’t want any NIT college (but I had applied for that) but didn’t get good NIT college. Then I started preparation for 2013 leaving all these behinds.

MS in IIT Madras paper

Somehow in October, I came to know there is a program MS in IIT Madras so I applied for that. I was thinking I will not get the call also but by luck, I got the call for MS in IIT Madras for written test and Interview. I tell about that to my best friend and she told me that God has done his work now it’s on me, how will I use the opportunity given by him. This word boosts me up and I started preparation for written and interview.

Nothing was roaming in mind only the thing I was thinking about my goal somehow 13 days completed and now it’s a time of journey as Madras is around 2400 km it took around 1 and a half day to complete my journey. I reached there at 2 a.m. When I entered the institute the atmosphere was totally different from outside Chennai (I don’t like the Chennai environment :P). Excellent campus students were roaming here and there looks like that the time was morning 10 am no buddy was sleeping I really loved that. I got the accommodation in one of the hostels. At that time I slept and then after sometime again start preparation. Then one roommate also came and we had some conversation he had 400 ranks that bother me because I was not expecting people such a good rank had not got admission anywhere. I had a conversation with somehow because I was curious to know how paper is set for the MS admission and many things that I got from senior (actually peoples are helpful there that increase the respect for these IIT’an in my heart). I had a conversation with many other candidates who came there for written and interview. All of them have a rank between 400 to 900. This thing really bothering me because they were better than me in gate 2012 and some of them had the experience o the interview there in June July session they were also sharing their experience. Now the day comes. At 8 a.m. we had an exam we reached (we means I and my roommates three persons).

After having breakfast exam started and there was two phase of written exam one was objective(actually that was not objective because there is no option in any question they are of fill in the blanks type) and another one was subjective. We had 80 minutes for both exams and at most 40 minutes for one of them. There was 20 question in objective all were compulsory from discrete TOC, C, Digital, Graph Theory, DAA and 4 question are in subjective all were compulsory (check this page for questions ) that was my luck or god was with me. I knew the solution the of all question in the objective that was just because gate 2013 preparation and the subjective question was also not so tough they were also easy at least for me. Written exam had over and we were waiting for the result around after 1 hours they announced their result. The feels which come after seeing my name in that list I can’t explain because I was considering myself at a very low level as all other were better than me.

But I did at that time one huddle had crossed. Now the time of next phase and important one interview, after around 30 minutes interviews started and after around 1.5 hours there was my interview. They were taking the interview for at least half an hour of each candidate. This was really bothering me (but it’s the fact more the time in the interview more the chances of getting clear that). I entered the room. There were 9 professors inside but I don’t know from where they had come. I was feeling relax at that time. I had to face the face questions of some of India’s best professors.

IIT Madras Interview Questions for MS admission:

  • They asked me about my graduation percentage, projects etc then told me to choose any subject from the list given to me. I told them Automata (my favorite :)).
  • Then they asked me which topic in automata I said “finite automata”,
  • the question asked within a second what is finite automata write its mathematical representation. I did this.
  • then after writing that again question came to write automata for binary mod 5 (they are looking at me like I am a dead body and they are vulture :P).
  • Then again they ask to write an automaton for the odd number of 1’s and even number of 0’s that was easy.
  • Then they asked me pumping lemma about the regular expression.
  • Then they told me to write a regular expression of same automata.
  • They asked me do u know about CFG I said yes.
  • Then they asked what is CFG then pumping lemma of CFL(I didn’t know the pumping lemma of CFL).
  • Then they asked me the proof that the union of two RE is RE.
  • Then asked, what is the union of CFL?
  •  Then question on equivalence power of non-deterministic and deterministic finite automata,
  • non-deterministic and deterministic PDA,
  •  non-deterministic and deterministic Turing machine,
  • many other questions write a CFL, which is deterministic

I showed some variation here I guess I was successful in impressing them then some more question about Turing machine and proofs and that the end of my interview.

Before leaving there room I pointed out the mistake in one question in the written exam. I told them about that (they accept that it was a mistake). Somehow my interview was fine from my side. That was my cent percent I could need to do better than that, but I was not sure whether they will call me or not.

After leaving from there I again started the preparation of gate 2013. But after 1 week I got the call for admission that was one of the happiest days of my life because I got what I was looking for.

That’s it guys just one thing use each opportunity given to you, who knows what God wants for you. And yes, be in preparation for interview rankers (250-1500). If you are not in preparation then it will be difficult for you. One thing that really helped me that I was in Gate 2013 preparation so I cleared the written there easily.
