Interview preparation tips for other job seekers - Prepare and stay confident

Round: Test
Experience: Only a few students will get shortlisted who do all the questions correctly.

Round: Other Interview
Experience: First 4 rounds on day 1 and this are just to shortlist for more rounds on some other day.
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.
Skill Tips: They will focus on almost all the concepts of computer science.

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.
