Bank document for H1B interview

[Codelock]

I just completed my Btech in August 2015. Since then, i've been working for a startup company.
Firstly. I want to ask that is Bank statement required for h1b interview? If yes, my next question is:
I have two bank accounts , from one I had made payments for courses like udemy,I.e. paid in USD. Should I take the statement of other account just to avoid any queries regarding foreign investment?

Note: This startup is not my h1b sponsor
