You need to up your background checking game because coinbaazar has/had full time sockpuppets here to promote their platform, not a good interviewee for this kind of interview which is sort of like a service feature or something, check this thread for reference:
https://bitcointalk.org/index.php?topic=5271725.0The questions asked aren't that coherent too, I would work on that. and maybe some follow up questions too in order to make the interview more engaging.
Any question you would want to ask , feel free... its but obvious not every interview covers all the aspects.. you come up with your questions and those will be answered satisfactorily
