1.They picked one project from resume and started discussion on it for few minutes.(You should be clear about your project flow and about your contribution in it). 2.In depth discussion on stack and queue. Then one question implement queue using stack(complete code), another one reverse string using queue(complete code + dry run), remove duplicates from array except its first occurrence. 3.Hashmap implementation, various hashing techniques (Be clear with stack, queue, hashmap). 4.asked me to explain almost all object oriented concepts with real world example. 5. Few questions on keywords like final(C), finally(java), public, private, protected these are the questions I remember from first round.Then they asked me if you have any questions. I asked about profile work, Technical analyst Program(TAP), work culture etc.It was almost 45-50 minutes.
