I had five interviews (two technical, two behavioral, and one company expectations). They have an incredibly senior organization: everyone is very sharp, technically versed, and confident in their respective spaces. Compared to the rest of the organization I was very junior. However, they still expressed confidence that I'd be a good fit given my background (part-time remote work with lots of autonomy). Celine (People Ops) was very helpful and kind during the interview process as well. If you have a background in remote work, and (preferably) are a more senior individual (although there might be exceptions for mid-level--as was the case for myself), then I'd recommend that you check out Platform.sh!

Multiple over the phone interviews with senior and lead developers that varied from direct QA to ambling technical conversations depending on the personality of the interviewer. A deep technical focus was more valued than interpersonal/workplace questions, being stumped on a question wasn't an immediate failure.
