Cloudflare System Engineer interview questions

Total 7+ rounds. First recruiter round. Rejected after second round(hiring manager). Recruiter round focussed on Cloudflare, comp details, rounds of interviews and few questions about profile HM: Why are you looking for a new role? Why cloudflare?

The process included about 8 interviews with different people but mostly with the team member. The technical questions were fair, not very hard. And the also the interviewers were polite and professional. However, the whole process tool about 10 hours, and it was scheduled in a week or two, so you need to allocate a huge amount of time. This was a big issue specially, if you need to plan it during the working hours. Once all the interviews finished, there was no update for a week, and then finally a cold email saying No! without any feedback or explanation. It's totally fine to say "No" in an interview process, but given 8 rounds of interviews and many hours, first the silence period and second, not providing any feedback and explanation was a negative experience.
