My experience was nothing like the rest of these comments. I suppose they've read these comments and since changed their process, or I got lucky.

Overall, the process was long, but very smooth, and the recruiters were very pleasant to deal with and quick to reply.

I had an initial phone screen where I was asked what roles I'd like to be considered for, and a few questions about my past experience, why Cloudflare, etc.

I had another phone interview with an engineering manager where we had a more in-depth chat about my resume, and he asked me a number of technical questions, followed by a quick walkthrough of an algorithm to a problem.

Two days later, I was scheduled for a technical Hangouts interview where I went through an interesting problem with the lead for the team I was being considered for.

Their last step in the interviewing process is to bring their candidates onsite.

I got to meet the team in the morning and had four small, one-hour interviews with the different members, covering a wide variety of topics:

• A technical chat with the team lead
• A basic architecture question
• A whiteboard coding problem
• A second, final architecture question

I went out to lunch with the team after two of the interviews, and it was a great way to meet everyone outside of an interview setting.

I got a phone call later that day with an offer.

I'd say if you're interested in Cloudflare, disregard the previous comments and apply anyways. It seems like they've changed their process.
