Very long, but also very well structured, good job. Involved a coding asessement that you have 3 hours for, but you could do it in like 2. The last question out of the 3 was a little bad in my opinion, It was this confusing 'dynamic programming' algorithm question that you either remember how to solve because you looked it up, or you dont. It also had a section where you explain your solutions which wasnt timed. Overall 9/10 for this stage. Then you get a take home assignment, for 2 weeks. We had chess (shogi actually) with slightly modified rules. It had super specific instructions and automated tests, They also held about 4 zoom calls here they give 'hints' for the assignment, which was nice, but i didnt need them because it was all very basic info. Then theres an interview if you were in the top something percent by unit tests passed (so if you passed 100% interview is guaranteed). The interview consisted of a 1h technical interview, where you mostly had to showcase your solution, and live coding where they ask you to add a feature. Then right after i had a 30 min behavioral interview with HR. Kind of didnt like that they were in row with no break, i was too exausted from the intensive technical interview to give my best performance on the behavioral. Overall process was incredibely transparent and well organized(with a few caveats).
