I applied through an employee referral. The process took 3 days. I interviewed at Red Hat (Charlotte, NC) in Jan 2015
Interview
Two phone interviews, about one hour each.
Neither were especially technical, we discussed the team they were hiring for, the experience and qualities they were looking for, and fairly standard questions for software engineers.
The first interview was with a software engineer on the team. He was friendly and, after looking over my experience, seemed to feel I would be a good fit. After the interview he passed me on to his supervisor.
The second interview was with his supervisor, the team lead. While he repeated many of the same questions as the first interview, the friendly casual air was replaced with that of an interrogation. Many of the questions I asked were taken in the most negative context possible, more than once derailing the interview into the interviewer venting about past team members.
I've heard nothing further about this job, but after the last interview I really didn't want to work with this man so I haven't followed up about it either.

What open source projects have you contributed to?
I applied through other source. The process took 4 weeks. I interviewed at Red Hat
Interview
Processo lineare, uno screening al telefono, un colloquio con un HR, un colloquio con il CTO o un altro senior, colloquio con il product owner, ma poi mi hanno fermato lì
Initially had the recruiter screening, followed by 2 rounds. One with the Principal Engineer and the other with a Senior Manager. Both went well. Unfortunately, they moved with another candidate.
I applied online. I interviewed at Red Hat (Boston, MA)
Interview
Applied on LinkedIn. Contacted by tech lead a few weeks later for an interview. Video call interview (with someone other than the tech lead who contacted me) scheduled to last 30 minutes, ended up lasting about 45 minutes because I was having a good conversation with the interviewer.
