Three rounds not including the initial video call with the technical recruiter. The first interview round the hiring manager, followed by two technical interviews conducted by senior engineers. In the second round after the introductions were over I had to remotely connect to a virtual machine and troubleshoot an issue. You have to have a good solid Linux admin skills and experience with typical app deployment issues (cert errors, port conflicts, file handlers) In the hands on interview the interviewer provided a list of symptoms which you used to troubleshoot.

You really have to know your Linux admin skills and have related field experience to get through this. You have to know systemctl, journalctl, OpenSSL -- a good command of Linux. Focus is not on coding (Go lang) though solving the problem will require some simple code modification, recompile, and restart of services. The last round was more of a theoretical technical interview. I discussed my experience and answered various scenario type questions. They were meant to gauge my thought process and hands on experience.

The process included typical questions like tell me about yourself and experience. What was the last thing that you worked on? What was the most challenging problem? Do you have experience with microservices? What did you use for communications?
