The technical part of the interview was an experience. The interviewer who was also the manager of the team I was interviewing for jumped right into a question without a preamble. The question was about an on-call alert and how I would handle it. It was a very general question focused on HTTP status codes. I have a lot of on-call experience. I know a company can leave on-call responsibilities indeterminate if allowed to. This is why when you deploy an app or service you ensure the process for troubleshooting it is documented. Create alerts for critical components, indeed, but you control what's deployed and how, so you can control how to handle errors, how to describe alerts, so that the problem is clearer for the person on-call who you woke up. Projects should have runbooks, alerts and errors should be handled in specific internal ways that provide information to people on-call. I went into these details with the interviewer but he had tunnel vision for his question and continued to focus on HTTP status codes. In the end, I refused to answer his questions because he did not answer mine. Why was I being woken up by this general error when we control the pipes? By the way, knowing a specific HTTP status code (and there many of them) does not mean you're experienced. It means a service has failed so many times that that general error has dug into your memory.
There was another person in the room with him, an intern. This intern then asked a coding question straight from a classroom. Reinvent something to do with strings like reversal or splicing, etc. Nothing wrong with that or the intern. This is more reflective of a manager who likes to bring interns to interviews or if not interns then someone who is believed to be more in touch with these academic coding questions.
There were other parts of the interview that were just fine. Those two points I think paint a clear picture of the type of employee who would thrive there. If you are young and just out school, try this place you might enjoy it. If you're older, raising a family, value your personal time, consider the company's product because it will tell you who they are.
