Online Test: 1 Problem Solving/DS Algo question was asked. Sufficient time was given to solve the question but it was recommended/mentioned that the question should not take more than 60 min to solve. Codepair Round: Questions on past experience and some technical questions (DS Algo/ Problem Solving) were asked, as it is codepair round, answer has to be implemented and successfully run. One technical question and its extension was asked Virtual F2F: 1: Past experience was discussed and then somewhat real-world open-ended problem solving question was asked, I guess this was asked to evaluate on thought process. Healthy discussion was involved to device various optimisation of the problem. 2. 2 F2F interview was more of DS Algo/Problem-Solving round. A real world problem was asked which was first to be solved through native DS/Algo concepts and then more engineering complexities were introduced, where I guess some design skills were also being tested. 3. 3 F2F interview focuses on System Design skills.
