After a phone screening, I got an on-site interview. There are basically three rounds with three different people at the same day. Each round is towards different directions. First round is basic algorithms, and second is more related to big data which third round is related to object-oriented programming. I was asked to implement the insertion method for binary search tree.

Applied online. Phone Interview. Reverse linked list, fibonacci series, linux command line arguments, Regex. moved onto onsite. Onsite had 4 rounds, OO design round - design a tic tac toe game. Data structure round - 2-3 tree insertion and deletion. 3rd round : some regex, was shown a 2 page code in perl for 5 minutes on timer and asked to explain what it does. more linux commands. 4th round : behavioral and open ended technical questions. Learnt from the hiring manager that I was rejected 7 days later. smooth process. testing obscure data structures wasnt expected.
