I applied online. The process took 6 weeks. I interviewed at Cloudflare (London, England) in May 2018
Interview
4 interviews with various members of the company (executive interview, cultural fit interview, two guys who would presumably be my direct supervisors). Quite unstructured but not in a way that was unsettling; the executive interview was PACKED with technical questions but the other interviews were all just "getting to know you"-type questions.
One of the most thorough interviews for a great company. There was a practical portion which was very interesting and seemed to really test ones skills and how they think through problems.
Interview questions [1]
Question 1
Network infrastructure type questions on how you would troubleshoot complex issues.
The hiring process was unnecessarily long and tedious. After several rounds of interviews, each more time-consuming than the last, the final interviewer suggested I apply for a completely different role, which was not what I originally applied for. This made me feel like my time was wasted and that they weren't clear about their needs from the start. Overall, the experience felt disorganized and frustrating.
