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

Skills: puzzle solving skills, programming skills, maths(basics)

Interview Preparation Tips

Round: Test
Experience: Aptitude Test: The company was open to students in CS, IT, Mtech(CS, IS), Mech, Meta and Mining with CGPA >= 6. It was an online aptitude test of roughly an hour. It contained general aptitude questions on logic and maths, with some emphasis on geometry. There were more questions than one could solve in the given time so speed was important.

Round: Technical Interview
Experience: Eleven people were shortlisted. In my case, the technical interview was longer than it was for others, possibly because my branch was CS. I was asked a few logical puzzles, given a program to write(very simple: to check whether a given number was an Armstrong number) and asked to explain my internships and projects, as well as my Major Project. I was also asked some basic questions on Data Structures, Operating Systems and Database Systems.

Round: HR Interview
Experience: Two people were selected for this round, and both were placed in the company. Here I was asked: What do you hope to be doing some years from now? What is your idea of a good organisation? I was asked to talk about my hobbies and interests, and asked to give examples of when I had worked in a team and what role I played. They also asked for location preference.

General Tips: Some general math practice, no specific resource.
Sometimes it's all right even if you do not get the answer to a puzzle, as long as you are able to demonstrate your thinking process to the interviewer. Often when an interviewer is asking you questions about subjects you have studied, they are not testing your knowledge, but giving you a chance to explain something that you know about.
Some general math practice and recalling basic geometry concepts would help for the aptitude test.
For the technical interview, it helps to have a couple of concepts you can explain really well in subjects like OS, Database, and knowing the basics of Data Structures is essential.
The technical interview was exhausting, only because it went on for a while. In hindsight, it was not that difficult compared to some other companies I've heard about.

Interview Preparation Tips

Round: Resume Shortlist
Experience: I had a standard resume for this company as per our institute placement cell norms.
I had put in a lot of emphasis on my extra-curricular activities while preparing my resume since my CGPA was less. While applying for the core companies I also mentioned about the projects that I had completed in the past few years. The main difference in my resume for different companies was related to the “Areas of Interest” and the subjects studied.

Round: Test
Experience: Even when I was preparing for CAT I always knew that my preparation for this exam would always help me with the aptitude tests that companies conduct as part of their recruitment process. And it was the case with most of the aptitude tests I gave during the placement season.
The written test consisted of some tricky mathematical puzzles. One of them that I remember was to find the minimum number of people required to detect the bottle containing the poison out of the 1000 given bottles. The test comprised of 50 such mathematical questions/puzzles and the time allotted was only 30 minutes. They also had aptitude based questions. Around 180 to 200 students appeared for the first round. The company short-listed only 24 candidates for the next round.
Tips: Preparation of puzzles for this company would be helpful.

Round: HR Interview
Experience: The second round was the interview round. The interview was divided into 2 parts. The first part was a mathematics quiz and the second was an aptitude quiz. They gave us the question set and asked us to solve them. There was no specific time allotted. We had to solve those questions and give it back to them. The questions were easy aptitude based questions. If there were some questions that we could not solve we were asked to state the approach that we adopted to solve those questions. After reviewing the paper, they started asking me some mathematical puzzles. There was one other question, I don’t remember the data exactly but it was related to a man and his movements along a downward going escalator. The man started moving up the escalator with a certain speed relative to the ground and then while coming down his speed increased by a certain given factor, I was asked to state the absolute speed of the man.
Then the interviewers moved on to the HR questions. They inquired about my internships that I did in my past years and asked me to share the experience that I had in each of them. I had done 2 internships which I told them about. They next asked me draw comparison between the two and state which I felt was the better of the two and why.
The company finally recruited 12 students.

General Tips: I would advise students to have a brief overview of few commonly asked puzzles in interviews. Preparation for aptitude tests before hand would be very helpful.
College Name: IIT ROORKEE
Motivation: I acquired the knowledge about the profile during the pre-placement talk. Also since the company had come last year as well and recruited one of my seniors from my department, I garnered some knowledge about the profile and the company from him.

Experience: I was interviewed for 2 technical rounds followed by a telephonic round which was taken by the GOC VP for more than an hour. Most of th questions were from the programming language Java but 1-2 questions were computer concept(Didn't remember the question as its been more than 5 years this interview was taken). The question was simple but the interviewer asked in a little tricky way which made the question tricky. I was able to give the answer hence due to this one question I got through.
