Average Positive San Francisco, CA

I started with a recruiter touchpoint, but the process felt a bit uneven right away—the conversation was rushed, and even though the recruiter explained the path pretty clearly, the overall cadence didn’t feel smooth. After that, I had a hiring-manager style discussion and then a technical round that felt more like a collaborative problem-solving session than something purely “LeetCode.” I was able to talk through my thinking with the interviewer while we worked, and the tone stayed conversational.

What stood out most was how the technical expectations weren’t just about knowing algorithms—they were also about implementation details. In my coding round, there was a real focus on getting input parsing right and not losing time once the discussion moved forward. The interviewers were friendly and supportive, and the whole vibe leaned toward teamwork: iterating together, clarifying requirements, and adjusting as we went.

Average Neutral Austin, TX

I started with an early recruiter conversation where we covered the basics—what the role was, compensation and logistics, and how the interview rounds would work. The discussion also circled back to my background, and I remember being asked why I was looking for a new role and specifically why I was interested in Cloudflare.

After that, the manager-style call format was pretty clear: the interviewer introduced themselves, I introduced my background, then we went through behavioral questions with time to ask questions at the end. It felt like a straightforward screening step designed to see fit and communication rather than to test deep technical depth.
