After applying, I was given an OA, and once I completed it I went straight into a small set of live rounds. The sequence ran through four technical interview rounds plus a behavioral interview with a manager. The topics and question style felt fairly standard across the whole process, which made it easier to know what to expect from round to round.

What I appreciated most was how smooth it was operationally—HR was responsive and kept things moving. The difficulty level I’d describe as easy overall, and it didn’t feel like the process was trying to be overly tricky.
