Came in expecting a by-the-numbers enterprise SaaS interview. Got something more interesting.
Five rounds total: recruiter screen (30 min, totally fine, she actually knew the job), technical phone screen with a senior eng (45 min, one medium-ish graph problem, nothing wild), then a virtual on-site spread over two days because of scheduling.
On-site was: coding (two problems, one array manipulation, one on trees, both mediums), system design, and two behavioral. The system design was the most interesting part. They gave me a prompt around building a permission system for a shared file storage product. Which, yeah, it's Box. They want to see if you've actually thought about access control at scale and not just "put it in the DB."
The behavioral panels surprised me most. They were genuinely curious about collaboration failures, not just wins. I was asked to describe a time I disagreed with a PM and how it played out. They dug in when I gave a surface answer. The second behavioral interviewer followed up with "what would you do differently" and then "why didn't you do that at the time." That's not a gotcha question but it's also not a lazy question.
Offer came in 10 days after the on-site. I didn't take it but the process itself was the most human big-company loop I've done in a while. Take that for what it's worth from someone who's pretty cynical about enterprise hiring.
