There were 3 rounds. Behavioral, Technical, and CEO. Each was about 45 minutes. Technical questions were pretty simple, some were about SSH, some were about git, some were about database, and some were about OOP.
The process took 2 weeks. I interviewed at ARCSys (Norfolk, VA) in Jan 2019
Interview
The interview process was really organized with calendar requests and clear instructions. The majority of the interview was spent talking about ARCSys as a whole, and I took some time to talk about my experience and what I was looking for.
