The first step was a video screening with a recruiter. Most question was about my previous experience. Mainly technical. He/She also presented the company to me and ask me why I want to work for Red Hat.
Next step was a technical interview (video conference) with three guys approximately two hours. Started asking same questions with the first interview about my technical experience. Then, bombed with a lot of too advanced language-based questions. A lot of them.
Overall, very professional deal with the candidate but too demanding...
