4 Interview Rounds

Interview Preparation Tips

Round: Resume Shortlist
Experience: Resumes are shorlisted based on GPA of 8.5 for Computer Science and Mathematics and Computing and 9.0 for Electronics and Electrical Engineering Students.

Round: Test
Experience: Questions were individually timed, and were a blend of very simple, interesting and tough questions. Most of them are based on Probability and Random Processes or Combinatorics. Some of them would be solvable by geometrical techniques, some by reduction and some by mere brute force!
Tips: I would recommend revising probability and permutations and combinations. If really interested, a book on Algorithmic Puzzles by Levitin and Levitin might help.
Duration: 120 minutes

Round: Puzzle Interview
Experience: The interview rounds consist of 6-7 telephonic interviews (on your mobile, so try to have a good connection) from different WQ offices around the world. Also, they start sharp at the time allotted (in my case, they started at 4 AM and I was late!), so be sure to be ready at the time.

Each round is of about 25 mins, with a 3 min chat about resume and the rest on puzzles/questions. About 2-3 puzzles can be asked during that time. The problems are algorithmic puzzles of the same kind but slightly tougher than those in the test. I recall one question that was solvable by application of Markov Chains, another was a variation of the Binary Search Algorithm.

There is no HR round!
Tips: The questions are tough, but you need to remember they are tough for everyone. The interviewer is more interested in your approach than your solution. So, keep talking to him while you attempt to work out the solution. He would keep providing you hints and help to get through those problems. Also, there are some very simple questions thrown in between tough questions, try to not get those wrong.

General Tips: Be conversant in algorithms and quantitative analysis.
Skills: Algorithms And Data Structures, Algorithmic Approach To Problem Solving, Quantitative Aptitude, Quant+Math
College Name: IIT Kharagpur
Motivation: Good work (if interested in mathematics and algorithms), opportunity to learn, good money
Funny Moments: I was late on morning of December 1, but since WQ had telephonic interview, the first interviewer called me when I was still cycling to the placement center in my institute. So, I had to park my cycle in the middle of the road. And my first interview was with me sitting on the ground near my hall in Kharagpur.
