first round was with the recruiter, pretty standard (introduce yourself + why cloudflare)
second round with hiring manager (mostly behavioural/sharing about experiences)
third + fourth round with team members and featured technical qns
First round was just the common screening, with common starting questions.
The coding interview was a common leetcode problem.
Did not pass that stage, so can not tell the rest.
The process was so long - took about 2 months from applying to hearing back after the final round. There were 3 interviews - first with the hiring manager and then 2 back-to-back with senior members of the team.
