This is a lengthier interview process, but you will feel informed throughout!
There's an initial conversation, a take home, a power day (think 6-8 different interviewers), and an interview with the COO before you get to the offer.
BetterUp is intentional about making a good technical and community hire, and you'll feel the hard work they put into their recruiting once you join the team.
My main recommendation is that there's more context provided for the power day of interviews (what to expect with each interviewer).
