Took roughly six weeks between arranging schedules. Approx a week to come back with feedback after each stage. First stage was a HR screening. Second stage was a time-limited coding exam (remote online using only particular languages - I chose Java). Third stage was an interview with an engineering manager. Didn't reach the fourth stage but it would have been interview with tech leads walking through coding and whiteboard problems. Overall it was a fair interview process that I couldn't fault. Interviewers were pleasant and as a company they are transparent in how they recruit. They value feedback and were happy to give me some at the end while also seeking mine. Unfortunately my technology familiarity in their particular language of choice didn't match the level of what they needed (Scala rather than just plain Java) but that's how it is sometimes and certainly no fault of the company seeking what they skills they need to hit the ground running.
