After a recruiter phone screen, I had a video interview with the hiring manager, and the pace stayed pretty steady from there. Next came a take-home code review exercise, which felt like it was aimed at how I think about real code rather than chasing quick algorithm tricks.

A week or so later, I moved into a final round that was all video and split into three distinct sessions. One part focused on culture fit, then I had a front-end technical conversation, and the last session was system design with the team. Overall it felt like a thoughtful, structured journey—especially compared with interviews that jump around without a clear through-line—and even though I didn’t receive an offer, the process had a clear logic to it.

I had one of those processes where the communication felt sharp and I always knew what was next. It moved through a phone screen first, then a manager interview, followed by a take-home coding challenge, and then a virtual onsite.

The take-home piece was the standout: it wasn’t presented as a quick algorithm speed test, and the overall sequence felt “gold standard” in how it was paced and explained. By the time I reached the onsite, the flow made sense, and the structure reduced that feeling of being tossed around between unrelated prompts.
