Cognizant Technology Solutions Interview Experience - FIEM KOLKATA, 6th & 7th September 2016
I am from ECE department and I am going to share my interview experience.
On 6th Sept AMCAT organized the aptitude test which consisted of 3 sections:
1. Verbal ability : 25 marks in 25 minutes.
2. Quantitative aptitude : 16 marks in 16 minutes.
3. Logical reasoning : 14 marks in 14 minutes.
Each and every section has cutoff.
For these sections, one can practice R.S Aggarwal, IndiaBix, Arun Sharma and there is software available on google play store from which you can practice. You may refer to R.K Kanodia Aptitude Book for GATE as this book is very handful if you want all these 3 combos inside a single book.
I can't recall the exact statistics, how many got selected for the technical round but it could be around 160 out of 350 (approx).
After the aptitude exam, they had organized a seminar which is must for all the students and also it is important for an individual as they might ask questions from the seminar as told by our seniors and teachers. Although I listened to the seminar reluctantly and more interested in knowing the bucks that they will pay which they told at the end of the seminar.
Next day was the interview day. The reporting time was 8 am and the cognizant team entered the premises at 8.50 around and there was a huge chaos regarding our 6th sem result as it was declared on the very same day. People running here and there to take the printout.
After all these hassles we settled ourself at SG Hall where our documents were verified and they were calling out names based on one's performance in the aptitude exam. I was 31st person. As soon as they called out my name I headed towards the interview panel.
Interviewer: Are you nervous?
Me: No (be confident to answer and don't show them that you are freaking. So fake it till you make it).
Interviewer: Tell me something about yourself that is not on your CV.
Me: I love to eat Biriyni.
Interviewer: Burst out laughing, ok! whats your fav restaurant and location?
Now let me tell you that I didn't mention any subject preferences in my CV whereas others had mentioned 2 or 3 subjects. So, she got a chance to exploit the whole ECE subjects and I am cursing myself for such moronic activity.
Interviewer: Ok now let me come to your subjects. Draw And gate using or and not?
Me: Drawn, actually u need to catch the crux here OR + NOT = NOR which is a universal GATE.
Interviewer: What is the difference between RAM and ROM and their various types?
Interviewer: Ok what is the difference between SRAM and DRAM and draw their internal architecture with BJT? Also, explain how it data is stored in it.
Me: The moment this question entered through my ears I was shattered. But appeared to be desperate and trying to draw it on paper although I knew I couldn't. At last, I gave up.
Ps: Don't show your ignorance blatantly. Try to convince them but evade bluffing.
Interviewer: What is TCP/IP?
Me: (since I don't have data communication as my optional subject my heart started throbbing at 5G speed. 2 back to back questions which I couldn't answer gave me a semi-heart attack)
Mam, I can't recall this answer but I will surely follow up with this answer after my interview.
Somewhat mobilized by my answer. She was hopping from one subject to another.
Now comes microprocessor.
Interviewer: Difference between microprocessor and microcontroller?
Interviewer: How many pins are there in 8086?
Interviewer: What is pipelining concept and how it is implemented in x86 architectures.
Interviewer: Features of 8086 that 8085 don't have?
Interviewer: Tell me some more subjects you are comfortable with.
Me: Signal system, solid state electronics, control system. (I knew she would rarely ask me questions from these subjects and my gambling was right, she moved to computer science)
Interviewer: In which language you are comfortable?
Me: C language.
Interviewer: Gave an inverted triangular pattern and told me to write the algorithm.
Interviewer: Ok now tell me what is the difference between singly and doubly linked list.
Interviewer: What is hashing?
Interviewer: Difference between queue using linked list to queue using array?
Me: Explained (how memories are allocated using array and linked list)
Interviewer: Difference between dequeue and enqueue.
Interviewer: Suppose you are provided with a linked list of unknown size and with only one traversal you have to print the middle element of the linked list? you are not allowed to use any other data structure ex. array.
Me: Told. (outsmarted the interview with my answer supported by a logic. But sorry I couldn't explain it here as it will be a 25 marks essay)
Interviewer: Ok I am over do you have and question for me.
Me: No mam. Thank you.
(2 more questions she asked which I couldn't answer but I can't remember it).
My interview went for almost 45 min and I thought I won't be able to make it to the HR round because of that 4 questions. But hopefully, with gods grace, I was the first one from ECE department to go for the HR round.
Interviewer: Tell me about yourself?
Interviewer: Tell me about Cognizant?
Interviewer: You have mentioned that you can motivate people so tell me where and under which circumstances you have motivated people.
Me: Shared real life experience.
Interviewer: Ok now tell me how flexible you are?
Me: Told. But sentences are poorly constructed.
I could be sniffed some disappointment from his side. And then he told me to give some concrete examples I tried my best to convince him and finally succeeded in my mission.
Interviewer: Are you ready to relocate?
Interviewer: Gave me a document. Please read it carefully and sign at the bottom.
Interviewer: Do you have any question for me?
Me: On which aspect I need to improve myself.
Interviewer: Told and explained how to EXCEL in corporate life where I lack, etc.
Me: Thank you.
Next day morning I got a mail from our TPO sir that I was selected for Cognizant campus interview.
Thank you for reading this.
