Did not ask much on a first interview, just described at length the project details - specifics, working hours, chances that I might be overqualified for this position. No technical questions were asked, though it was supposed to be technical interview (apparently, my CV was enough). Then three phone interviews followed - with prospected project manager, with prospected customer (partner of Luxoft) and then with prospected project manager again. The prospected customer/partner who asked technical questions, however, not quite difficult, but I might have made a confusing impression.
