United StatesPosted Nov 2025 · Candidate report, summarized by Dataford

I started with a behavioral screen, and then the technical part was fairly simple—an algorithm question that didn’t seem designed to be a tough brain-teaser.

The part that made the experience frustrating wasn’t the difficulty of the content, though. Communication was poor and the interview kept getting delayed.

I ended up having to reach out just to get any updates, which made the whole flow feel inefficient and a bit stressful. The difficulty level overall landed as easy, but the delays and lack of clear communication undercut the smoothness of the actual questions. I remember feeling like I was waiting more than I was interviewing. In the end, the technical section was manageable, but the process logistics were what stuck with me.
