Process is very long, it consist of 1 hr screening and 3 live-coding interviews in HackerRank. The live coding are ok-eish described, you can always ask some clarification questions to the person that interview you. You have to implement an interface - so that's really nice oppose to some algorithms live coding. The interviewers are nice and provide help.
The only thing that I dislike is the time consumption. 3 live-coding interviews 1,5h each and I waited in-between for 3-4 days to get the interview result. That's a really long process.
