I was referred via the Ambassador Referral program. I was told by my manager that there were several Technical Writer positions available. During the initial phone screen the recruiter did not seem enthused and unprepared. He then told me that someone else had been chosen for the first opening. I thought that was the end of my interview opportunities at Red Hat. Then, a week later he contacted me again about another TW position. I had a 30 minute interview with the hiring manager who was very professional and likable. There was also a writing assessment which was not as intimidating as I had imagined. Basically, multiple choice grammar and clarity questions and rewriting several product descriptions. Within an hour after speaking with her, a different recruiter contacted me about the next steps in the interview process. The next interview was a 2 hour interview with 4 team members. Many of the questions were competency based questions. So, look those up online and be prepared to give examples from previous jobs. A week after interview 3 I received a job offer.
