Previous email contacts, they told me they were interested in my profile and wanted more details and my CV. Appointed a phone interview, typical big company questions ("why did you leave your last job?" "present yourself") and some technical questions ("difference between hardware and software" "name some videocard brands in the market"). About 25min. total. After that, next day they appointed an on-site interview with a board of three, but HR representative was missing, so the interview was conducted by two team members. It was similar to the phone interview but 90min. long, asking about strong points, weakness, milestones in your past jobs, how did you interact with your superiors and how was the feedback, and one technical test, situational question.
