I applied through an employee referral. The process took 1 week. I interviewed at Red Hat in Jul 2011
Interview
The entire process was very easy and friendly. Red Hat puts quite a bit of weight into employee referrals. My initial contacts were with the same person in HR who was very responsive over email and phone. Since I don't live near the main headquarters, I was able to do all of my interviews over the phone. One of which, I went into one of their sales offices to use a conference room. I had 3 or 4 interviews with engineers and direct managers on the team (nobody from HR). They asked a few stock scenario type questions ("Tell me about a time you ..."). Then the rest of the time was technical discussions (didn't really feel like an interview, just like chatting over coffee). The interviewers had obviously read my resume and dug into some projects and were curious about details.
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.
