1. The first technical round had an object oriented design question (along the lines of designing classes for an apartment system) followed by a question for printing numbers in a triangular pattern. 2. The second round was interesting. The interviewer started with a trick math question. He followed up with a dynamic programming question. Didn't stop there. He asked around 9-10 questions in total covering topics like trees, graphs etc. Most of them didn't involve coding and the interviewer was satisfied with an explanation and pseudocode. All the questions were simple except for the math trick questions. 3. The two manager rounds had situational questions, discussions of general design approaches.
