I applied online. The process took 2 weeks. I interviewed at Cloudflare in Aug 2024
Interview
They sent me an online hackerrank test. Two problems with two hours to complete them. Easy to moderate difficulty, one had enough steps to take an hour. Thought I did well. After the test they emailed, wanted to speak with me and asked for my availability. After submitting my availability, I was ghosted.
I applied through a recruiter. I interviewed at Cloudflare (Lisbon, Lisbon District) in Jan 2026
Interview
Super cool process, with multiple stages and comprehensive people. Although I’ve not been selected, it was a nice experience and I would love to participate in the process again in the future
I applied online. I interviewed at Cloudflare in Jan 2026
Interview
First step was the interview with hiring manager, next step - live coding, then I dropped off because of poor communication from the recruiter's side.
Technical people are cool and very friendly, I didn't feel nervous with them and got a lot of information about the projects they work on.
But HR side requires improvement. They can ignore your re-scheduling request or skip the call without prior notification.
