First I was given a search algorithm assessment and I have completed it in 4 days. The second round is on the technical interview, which is easy where they asked me programming question on binary trees (very easy one). trust me this question even a person who dosnt know to program but knows what is binary can solve it. I screwed up this easy question. The interviewer is very kind and he asked some software engineering questions like multi threading, coredump, etc. some differentiation questions like what does double diff mean when finding maximum of equation. The interviwer is kind and very interactive. But i didint get an offer, I think because I didnt solve problem properly. But, still I have answered all the questions and this is outrageous, caz after putting through a long interviewing process they just cut me off caz of didint answer a small question.
