First round: solve a coding challenge with a senior developer Second round: HR interview (cultural fit) Third round: Part 1) 1hr interview asking questions about CV Part2) 1 hr coding test with senior developer I was told that part 2 of the third round interview would be an application design interview. I asked them if they could give me some more details but they never got back to me. When I sat down to do the application design interview it turns out that it was actually just another coding test and had nothing to do with application design. Also, there was no mention before the interview that you could only do the test in Python, JavaScript or Ruby
