I had a phone interview and then a 1 on 1 interview with the hiring manger and one other person. The following day I had a phone interview with corporate HR. I asked the hiring manager for a salary range and we were within my target salary. When I spoke to HR they seemed concerned at the amount of salary that was quoted to me. Overall the interview process went well. My concern is that it took over 30 days to get a final response on the position when they explicitly told me that wanted to fill this position right away. F5 personnel were pleasant and the building and location was very pleasant.
