interviewing for a senior SWE role on their technology team in 3 weeks. mostly seeing older threads so dropping this here to get fresher data.
if you've interviewed at BlackRock in the last 6-12 months: how many rounds, what was the format, how heavy was the behavioral component? any surprises? what did you wish you'd prepped differently?
i'm in fintech so i'm not coming in cold on the domain but i know their loop can be its own thing. any signals on what they weigh most in the debrief would help too.

interviewed for a mid-level fintech SWE role there about 8 months ago. 5 rounds: recruiter, technical phone, then virtual onsite with coding (2 rounds), system design, and behavioral. behavioral was genuinely the round where i felt most evaluated, more than the coding. they asked a lot about how i handle uncertainty and disagreement. come with specific examples.

i interviewed for a platform engineering role last spring. they care a lot about observability and reliability patterns. one interviewer spent 20 minutes on how i'd instrument a critical batch job. it wasn't textbook system design, more applied. also: the behavioral round asked about a time i pushed back on a deadline. have a real answer for that.

they weight behavioral pretty heavily even for IC roles. more so than my FAANG experience. it felt like they're screening for someone who fits a specific operating culture, methodical, risk-aware, not a 'move fast' type. if you have stories about careful decision-making under uncertainty those land better than 'i shipped X in 2 weeks' narratives.
