Tips: They will focus on almost all the concepts of computer science.You need to practice a lot and start it right now. Should be easy if you have prepared well enough. Use your holidays to start preparing for placements.

General Tips: Sooner you start, better your placement will be as lack of practice & last day study works only for exams but never for interviews. You'll get enough time to prepare for interviews once you get shortlisted. Focus on it even if you are placed already.

Round: Technical Interview
Experience: On-site interview (5 hours).

4 back-to-back 45-minute coding interviews, followed by a design interview, with a lunch break with a Googler in the middle.

The first coding interview was a set of (surprisingly) trivial (no algorithms needed) incremental coding questions.

The two next coding interviews were problems straight from the "Cracking the coding interview" book. Even though I divulged that I'd solved pretty much exactly the same problem before, they didn't give me an alternative problem and I quickly coded up a general and optimal solution for the problems. Follow-up in-depth questions were minimal and not hard.

The last coding question was a pure algorithm question related to search trees/tries. No coding required, spent the whole time reasoning about the most effective algorithm. This was a bit of a brain twister.

The design question was related to high-level system design (not OO design) for storage and search in geographic data. Focus was effective search as well as scalability both in traffic and data volumes.

Tips: Read "Cracking the coding interview" or other similar literature. Solve all the problems and you should be good to go. If you solve a bunch of problems at HackerRank (or similar) as well, you'll have the added bonus of training on how to generalize the algorithms.

Round: Group Discussion
Experience: Nicely organized GD, civilized and intellectual GD group, discussion rich topic
Tips: Allow others to speak when they have something to say. Do try to push your way in if someone is talking too long or talking gibberish. Do not push your point too much, however, present logical arguments in favor. Try to draw similarities from what others say. Try to include all.

Round: HR Interview
Experience: Friendly HR interviewer. Non-direct questions but not too difficult.
Tips: Answer all questions honestly but be polite. Don't present too strong views, you are too young for that. Don't repeat content with different words, but be elaborate enough to let the interviewer know you.

Round: Guesstimate Interview
Tips: Read up some guesstimates and case studies before placements, discuss some with friends too. Open up your mind while guesstimating. Speak all that comes to your head, and vocally sift through them to get the logical and pursue-able approaches. The interviewer should get a complete idea of your analytical approach.
