Terrible experience.
First round went great, I met with a manager who was very friendly, we discussed the industry Twingate is operating in and what life at Twingate was like.
Second round was a coding challenge, you get about three hours to implement a faux memory allocator. Before the round began, I asked if I could use AI (Claude Code) to implement a solution, and that was approved. Early the next week I received an interview request for the "next round" which would be a code review of this project and an additional coding exercise.
Third round is where the process turned sour. It was supposed to be a "code review" but in actuality the "interviewer" just had me share screen while directing me to various parts of the code where there were bugs or inconsistencies, for example where Claude had hallucinated something into the README that actually wasn't present in the codebase, without actually asking me about my own contributions or prompting approach. It felt like the interviewer had already made up his mind before the interview started, and just wanted to embarrass me.
Would recommend staying far away from this company if this is representative of the culture here.
