NANOWAVE Technologies interview questions

I first interviewed with the management in Ottawa and some of the Toronto staff joining remotely. The interview went well and the Ottawa management were very professional and personable. I was then called back for a second interview with the CEO, Miller, in Toronto. I got grilled pretty hard which is fine. However towards the end of the interview he made a very unprofessional threat regarding if anything in my resume was found to be inaccurate. It seems reports that this guy is a tyrant are accurate.
