There were 2 interviews, 2 1:30 minute coding challenges, and one of the interviews was an "Architecture interview".

The phone screening before the actual 1st interview and the 1st culture interview were a breeze. The coding problems were medium difficulty, but they wanted you to be able to write down the Time and Space Complexity of your solutions.

The architecture interview was, without a doubt, the worst interview I have ever done. My interview was being done by someone who was clearly inexperienced in people management and interviews, and was being shadowed by a more senior HR person in what they called 'Reverse shadowing.' The problem statement given was simple: architect a rate limiting system. This was the first time I had ever been interviewed in this manner, so I attempted to approach the problem by gaining as much insight into 'how' the system should work, what kind of scale it should have, was the system cost sensitive, and could I use existing tools, or did I need to be as agnostic as possible, giving pseudo-code answers.

Well, my attempt to understand what questions the junior interviewer was asking was met with exasperation and frustration directed at me. My attempts to further clarify the problem led to further enraging the junior interviewer, while the senior interviewer sat in total silence, as I was borderline yelled at for not understanding how to give a different answer on how I would architect this silly little spur-of-the-moment system. And attempting to draw diagrams with my mouse and speak at the same time only made the system worse. By 25 minutes in, it was obvious I would not be getting the job, given how frustrated the junior but lead interviewer was, so I thought about just calling it off. I persisted for the remainder of the hour, only managing to slightly understand the goal of the interview.

I considered asking for another interview with someone more experienced, given how well the first few had gone, but I decided against it if this was how potential talent was treated.

How do you deal with failure?
