The interview process
Described in candidates’ own words.
“I only had the online assessment. I heard that sometimes there are multiple rounds, but I haven't heard back yet, though not much time has passed.”Candidate-reported process
“It was a standard coding interview that lasted about an hour. I was asked to go over my previous work experience briefly, then tackle two medium-difficulty LeetCode problems and one question about general data structures. The interviewer's English wasn't great and they didn't seem very into it.”Candidate-reported process
“I had two rounds with two really great people. We had nice chats, and they gave me plenty of time to ask my questions. They were also super flexible and quick to schedule and reschedule interviews.”Candidate-reported processMore reports lockedRead 300+ more interview experiences
