I applied through a recruiter. The process took 4 weeks. I interviewed at Barclays (Prague) in May 2015
Interview
The first is medium-complexity on-line tests for C# and OOP. The second is interview with several team leaders simultaneously. The interview was easy technically, but more important is first impression of verbal skills. It looks really crucial compared to other stuff.

Interview
the interview is very difficult: 3 stages of interview: video call interview asking questions, technical test and in office face-to-face interview. The questions are related to deep understanding of C++, data structures and algorithm. For example, why STL don't use virtual functions
