It took a while. First of all, I submited my resume using web form on redhat.com page. I had no response from HR or anything. I was waiting indefinitely. Only contract with team members I wanted to work with keept my hope. I had few interviews with team leader and second team member. Then I've got short talk with my manager. The most unexpected part was the contract with recruiter. I was accepted by team members and manager in November. The recruiter come back to me in February. So after more than three months HR team was able to proceed whole process. After negotiations things went smoothly, but waiting was a nightmare.
