A very simple online screening, 4-5 questions that were very basic. Got an email to schedule the 2nd round phone interview. Was told that it would be only one interview of 45 mins. technical in nature. Topics could include algorithms, data structures, object oriented programming etc. Interviewer was calm and asked only 1 question. Gave 2 different answers and their complexities. Was asked to code one approach. Kept speaking out loud when writing code, telling him what I was thinking and doing. Reviewed my code once after I finished writing. Question was moderate difficulty. Interviewer was still calm, so couldnt infer any result of the interview.
