Applied on their website. There's a total of 5 steps in the interview. First is an HR call, then a weekly coding challenge, then an on-site team lead interview, then CTO and finally CEO. The coding challenge covers all aspects of the related title and can be done in the given time frame but be prepared to put in many hours if you intend to make it polished.

On-site interview with the team was in good atmosphere, with several questions related to the weekly project, related position and also some Git questions. All in all it was a pleasant experience although I was rejected. The only thing I didn't like is that rejection email listed no reasons for the rejection and was too generic.
