Recruiter screen and 1 hour coding interview. If you're not 100% on the first attempt they may have you complete a second attempt. I was generally frustrated with both interviewers; there were instances where I would be thinking or working through a problem out loud, and it was clear that they were staring at the solution on their screen and were on the edge of their seats to either guide me or ask me a question to push me in a certain direction. In the end I solved both problems, but was not passed to the next round.

Question 1
Both challenges were general logic challenges in your programming language of choice, but also not related to security.
