Found the job listing on the F5 website, and sent my resume via email. The next day I had a message in my inbox from a recruiter who set up an initial screen. She called me the next day and took about 15 minutes of the usual get to know you questions. She emailed me later that day with info on another call with the hiring manager. The HM called me and took about 20 minutes of get to know you and some initial technical questions. He then set me up with a senior technical member of the team for a technical interview. Interview lasted about an hour and was very technical, all over the phone. I later received an email stating that my knowledge wasn't deep enough and would not be going any further.
