Hi @smt88 - thanks for your reply. Makes sense to what you said. I can imagine some people may be uncomfortable taking the mock interview. However I have a different way to implement it, which is pleasant for both interviewer and interviewee. I started two companies so know very well how difficult is it to sell products to users. Thats why I want to get some feedback before starting a new idea. I am a developer so I put one pager website (I am not sure if I am allowed to share links here so did not) to seek interest but your suggestion of posting on craigslist is excellent. Thanks a lot for your thoughts.
