Two Stages. In the fist stage there were multiple tests. The tests checked quantitative skills, data interpretation, reasoning and attention to details. They also tested knowledge of algorithms and their implementation. In the second stage, interviews were done for candidates who cleared the first stage. I had 3 rounds of interview. The first one was a coding interview. The second was also a coding interview but some puzzles were asked as well. The third round was an HR interview. All of them were 1:1 interviews.
