Interview Preparation Tips

Round: Test
Experience: It was basic aptitude test with two parts
part i) General test: 40 questions, 20 minutes
part ii) Technical test: 30 questions, 20 minutes
both of the test were easy.
Tips: practice for time and work, time speed and distance, some what geometry and mensuration, and mainly search for 3dplm and geometric previous year questions
Duration: 40 minutes

Round: Technical Interview
Experience: It was interview of 32 candidates --> 2 day process
My interview took around 60-70 minutes. Initially I was little nervous, so interviewer told me to be relax and calm (this process is ice breaking process so that candidate can give answers in his normal way). then he started with introduce yourself, for all interviews this is the first question.
my introduction was not completed as my actual interview began with my achievements. First question was about codevita what is codevita, what types of problem were asked and all that (Codevita is competition organised by TCS every year and it was mentioned in my resume), so after listening to problem statement he changed the problem in his way and asked me to make a program. he asked me one question on java but I am unable to recall it right now. Next was puzzle -> Given 9 identical coins what number of minimum comparisons between them will be required to determine one of the heavier coin.
I solved this puzzle and i think i was the first one to answer it correctly, so interviewer played the next move.. and that was to make a program for this where input was no. of coins and output is no. of comparisons required. (this was the important question of my interview due to which i got selected).
he asked about my family, my future plan specially post graduation (he tried to asked me 2-3 times about my post graduation plans)
Tips: Be confident,
always be ready for data structure, C, puzzles.

Round: Group Activity
Experience: this was unique round took around 2hr.
it was group discussion on puzzle and one program between all candidates and HR also.
Puzzle: there are 25 horses and you have to find top 3, but problem is track has a size of 5 horses so what is minimum no. of races requiered to find top 3.
Program: Date validation (this took around 1 and half hour)
overall motto behind this round was checking candidate's thinking capability, and how he behaves in a group.
Tips: Be confident and share your thoughts, as i think every company basically focuses on how good your thought process is.

Skills: Data Structure, logical reasoning, programming
College Name: Government College Of Engineering, Aurangabad
Funny Moments: in my second round, for program of date validation
every one was talking about creating a program, but i am bit lazy, so i gave my answer that create a reference of Date class and insert the details using that reference if error occured then that date is not valid

on this HR replied me "anyways you are selected "

and after the end of session everyone came to me to shake hand but i was thinking that was joke and i did not shook hand with anyone.

Interview Preparation Tips

Round: Test
Experience: general wareness consists of one liner questions that are easy but the time provided would be less... say 20 mins for 40-50 questions..this section basically checks your speed
aptitude consists of general aptitude questions basically maths , geometry and reasoning which are also easy and time provided is sufficient
Tips: dont loose your calm and avoid any silly mistakes...... try to improve your speed by regular practice coz the questions provided are easy and rest assured that you are capable enough to solve then right but all that you need to go ahead in this cut throat competition is you speed ,your confidence and your calm mind
P.S - this tip applies to almost all aptitude tests for any campus recruitment

Round: HR Interview
Experience: Hr questions are basically those questions to which you could answer easily coz they are questions about you.its as if you are introducing yourself to a stranger but then try to be a bit witty in your answers ..thats what catches the attention of the interviewer the most
Tips: do not go to an interview with the same old conventional mugged up answers....IT should be like you are meeting a person for the first time and you need to impress him/her with your answers

Round: Technical Interview
Experience: the technical interview was a bit of everything infact.. YOU need to know your branch basics...you need to know the maths studied in 9th and 10th standard....you need to know a bit of programming (not compulsory)....and ya try to go through some google puzzles before going for the interview...or at least try to use a bit of your logical sense for such questions
Tips: I know it becomes hard to be able to be a master in all fields....but at least dnt try to look dumb or arrogant by just saying i dont know....show them the attitude that you are atleast trying to solve the question even if you dont know how to ..beforehand,,,,,,and a huge tip is that you are the one who actually decides which way your interview turns to...the way you answer,,the terms you use ...etc is what helps the interviewer to frame the next question from your answer itself..so always try to bring up those points about which you want your interviewer to ask questions to you

Interview Tips & Stories

Why are women still asked such personal questions in interview?
I recently went for an interview… and honestly, m still trying to process what just happened. Instead of being asked about my skills, experience, or how I could add value to the company… the questions took a totally unexpected turn. The interviewer started asking things like When are you getting married? Are you engaged? And m sure, if I had said I was married, the next question would’ve been How long have you been married? What does my personal life have to do with the job m applying for? This is where I felt the gender discrimination hit hard. These types of questions are so casually thrown at women during interviews but are they ever asked to men? No one asks male candidates if they’re planning a wedding or how old their kids are. So why is it okay to ask women? Can we please stop normalising this kind of behaviour in interviews? Our careers shouldn’t be judged by our relationship status. Period.

Interview Questionnaire 

2 Questions

  • Q1. Algorithm and Trick questions on Java
  • Q2. Your future interest, interaction capabilities

Interview Preparation Tips

Round: Resume Shortlist
Experience: Mention only those projects/works which you feel fully confident on, let any question be thrown your way.
Believe me, a simple project explained in a good way is better than a complex project that scares you going into the details.
Tips: A little bit of extra activities (sports/music) helps them picture you as not a total nerd, which might help in front of some interviewers.

Round: Interview
Experience: They will mostly try to trick you here, even if you are right, they will make you doubt yourself. It's just about believing oneself and answering in one go.
Tips: Stick to your answers if you feel it's right, changing it again and again won't do you much good.

Round: Interview
Experience: This is where you have to be most careful, what they seek is just your interest in the company or infact passion for their work and not leaving them mid-way for higher studies or startup plans.
Tips: Diverting talks to some extra-currics might help a lot here specially if they have interest in that too, like the one, I was giving interview to, was wearing a Barcelona cap and I had mentioned that I played football at Inter-Hostel level. So we talked about the recent Premier league for like 10 minutes and the mood was really lightened, thanks to that.

General Tips: It is never too late to be what you might have been.
Skills: Algorithms, Java, Interaction Skills, coding, C, C++
College Name: IIT DELHI
Motivation: The technology (Social-Media Management) they are working on is really interesting to know more about and can be a future pioneer in the coming days.
Funny Moments: One of the interviewer I became so friendly with, mid-way through the interview that we added each other right there on facebook.

I appeared for an interview in Aug 2016.

Interview Preparation Tips

Round: Test
Experience: The questions were tricky. We were given a paragraph and after reading it, a statement was given to us and we were asked to say if it is true, false or cannot say. The structure of the statement put us into a a tough place. So practice of such kind of questions is necessary.

For data interpretation questions a good hand on basic statistical mathematics is needed. One has to be quick because of the time crunch. The questions were approachable

Round: Technical Interview
Experience: In this round my resume was scanned and I was required to speak about myself, my projects and explain certain areas of my resume. The interviewer picked up one of my basic project, surprisingly, and asked me to elaborate on it. He asked me how I can improve the project. And I had to write a code to make that change. Basically, one should have a good idea about the projects they've done/ mentioned in their resume. And know it in detail.

Few questions on data structures. Prepare well for coding type questions and data structures.

Round: Puzzle Interview
Experience: The interviewer asked me two puzzles. They were moderate level. And also luckily he was helpful whenever I got stuck.

Round: HR Interview
Experience: HR round was good. Basic questions like " tell me more about yourself", brief information about my past history, college life, extra curricular activities. In the end she asked me, "should we hire you?" And I lightly answered " why not!" So it was a good interview overall.
