I had a call with HR first, then a peer-interview with engineering managers and then three interviews with CTO, COO and CEO. The process went smooth and quite fast (2-3 weeks in total).

The entire process was incredibly smooth and fast, around two weeks from first contact to offer. First I got to talk to two engineers with whom I had a very enjoyable conversation that felt more like diving into some technical topics together, rather than a stressful interview. This stage also included a short coding challenge. After that I talked to the CEO, CTO and COO, who laid out the company vision and conducted additional small coding tests and behavioral questions. Overall, one of the most enjoyable interview processes I have gone through.
