WatchGuard Technologies Senior Revenue Accountant interview questions

Received email from corporate recruiter to set up a phone interview. Phone interview questions were fairly standard, brief introduction and quick summary of professional experience. Interviewer asked some very specific questions about certain Sarbanes sections around revenue recognition. Also focused heavily on the various systems they used and asked whether I had experience with those systems. This seemed to weighted much more heavily than I was expecting. Unfortunately, I hadn't had direct experience with their systems, and I think that was the deal breaker.
