Two phone calls (HR recruiter and manager), online test (90~120 minutes of algorithms where correctness AND performance is evaluated) followed by a half a day interview loop with 4 different people where many things are discussed (expectations, responsabilities, culture fit, some more technical questions, etc.). Got an offer exactly one week following the interview loop after they called my references. It really felt like they tried to make sure you're skilled and that you'll fit in well with the team and their culture. Which is encouraging.
