I applied through a recruiter. The process took 1 week. I interviewed at Raiffeisen Bank International (Warschau, Masowien) in Jul 2013
Interview
very great atmosphere, first phone call, then invitation to personal interview with supervisor and other employees. If the position requires language skills, be prepare as they will test them. No big issue but its better to be prepared. They also check your skills aligned with the position you apply for, there might be a written test or questions.
