I applied in mid-December 2016 and was contacted by an F5 recruiter in mid-January 2017. The recruiter set up an interview with a software engineer. The interview lasted for about 20-30 minutes. I was asked to write a simple C program on Collabedit.

At the end of the interview, the interviewer gave me positive feedback. He said I should expect to be called for an on-site interview.

After a couple of days, the recruiter reached out to me and asked for my availability for an on-site interview. After I sent him days/times, he replied, saying that he made a mistake in his previous email and that he had not received a final decision yet for my interview from the hiring manager. It could have been a genuine mistake, but imagine how you would feel to be told it was a mistake after you rescheduled other interviews for this one.

I emailed the recruiter a few times, and he told me there was no update. Then, in late March 2017, I received a generic rejection email.
