I applied through an employee referral. The process took 2 months. I interviewed at Gazprom (Belgrade, Central Serbia) in Jul 2013
Interview
Too long and detailed. There are lot of steps, starting from HR, and a few interviews with functional managers, and ending with Internal Security. I did not find sense for such long selection process. Also, they like to negotiate about salaries, so put some higher expectation in order to have room for maneuver.
Interview questions [1]
Question 1
Standard questions from all interviews. There is one surprisingly interview with local security guys.
