Coding test + IQ style test. After that, scheduled an entire half day of interview. Only had one interview before being rejected. Interviewer was not the best, kept asking "and how can you improve this code" without even leading to what he might want to answer about. At one stage I had suggested multithreading, and he said dont worry about that, and then later wanted that as an answer.

Take home test was quite difficult. Three leetcode hards in 2 hours. Then a mental maths and reasoning test. Then a super day consisting of pair programming, systems design and a white board exercise. If you don't pass any interview on the superday your interview ends there. I bombed the pair programming, question was not that hard but I choked.
