Recent Anthropic interview experiences
Full loops shared by candidates, every round included.
Anthropic — a narrow coding pass, then a 40-min HM behavioral round
I barely passed Anthropic's phone coding round, then got a 40-minute hiring-manager round that was all classic behavioral. One note on a concurrency prep hint that never actually came up. Still waiting on the result.
Anthropic onsite — "why Anthropic", a cloud-capacity data analysis, and SQL
A non-SWE-flavored loop that surprised people: heavy on culture fit plus a data-analysis task that needed some cloud-capacity intuition, and some SQL — but no traditional coding or system-design round. Commenters kept asking what role this even was.
Anthropic "Coding Interview with Claude" — the new work-with-AI format
Got Anthropic's newer interview format where the entire point is writing and reviewing code using AI tools — tool access is provided and you don't need to set anything up in advance. I applied through the online application; best guess is it's an infra role. Sharing the actual prompt they sent since a few people hadn't seen this format.
