2 telephonic followed by 3 f-2-f interviews. Telephonic interviews were mainly focused on DS and Algos. The interviewers were helpful and would guide you to a correct solution if you show some initial approach. Questions were to find next highest palindrome, finding whether numbers in an array sum up to k, a few questions on sorting and binary search. The f-2-f interviews had problems around tree traversals, recursion, divide and conquer approach and some puzzles. The puzzles were random and unless you have read them earlier, it is going to be very hard to come up with an answer. If the company wants to hire good thoughtful people, they need to fix this aspect of their interview process.

I applied through e-litmus. There was a written test(MCQ) and a programming test. Written test had questions from algorithms, OS, networking , data structures, compilers etc. you can't wake up one day and crack the interview. It needs clarity of almost all comp sc subjects. There were 42 MCQs and 1 programming test.
