Luxoft Product Owner/Manager interview questions

The manager then asked me some questions about experience and when I( tried to find out more about the role, responsibilities and team structure, the guy said he can't answer that but that the "client" would be able to answer that. (wth) After only a short time he said he thinks I'm 'suited' and the next stage would be with the 'client' who could answer all questions I have. Then when I asked the HR person when would this be she said the hiring manager is back the following week. Now I thought I was initially speaking to the hiring manager. Never heard back from them. If this is how they manage the candidate hiring process then I wonder what happens elsewhere in the company...
