Quite a long interview process. First stage was an at-home coding test, followed by a phone screen with a senior dev, followed by a day of 4 interviews onsite (including a coding challenge). The process was smooth and I was kept in the loop the entire time.

They have a very high bar though. They organise a call whether or not you are successful to give you feedback on each interview. In my case, I passed every interview with flying colours except one, but I was rejected for spending too much time going down the wrong path in the whiteboarding interview (despite finding an efficient solution in the end).

I would say that the process is difficult mainly due to the sheer amount of interviews you have to do. None of the individual interviews are too bad.

The process included data modelling, product questions, typical culture questions about past projects, and whiteboarding that was nothing too difficult.
