I applied through a recruitment agency. I was contacted by the agency that they had a potential match. Most of the details of the interview were coordinated through the agency.

It was all handled through a recruiter who had reached out to me. He was very thorough in prepping me for the interview process. I interviewed with 5 people and it was pretty laid back and conversational. Started off with introductions, then they told me about the firm. After that they asked about my experience thus far. They asked about my technical skills, software experience, etc. Pretty general, straightforward questions. Following the interview they asked me to complete a revit assessment. They gave me the option to do it in the office or proctored. I did it proctored and overall it was a smooth process. It isn't a "test" that you can fail, it's just so they know what level of skill you'd be coming in with. They give you a revit doc with instructions on it and have you complete various tasks. If you don't know what to do you just tell them and they walk you through it. Nothing to be nervous about. I really liked the firm and seriously considered accepting the position, but it was too far of a commute
