InnoEye Technologies Senior Android Developer interview questions

Worst thing is they had rescheduled my interview for five times and each time i intimated after reaching their office so at 6th time they finally got someone who can take interview, Questions were very basic covering android and java as well. After almost 20 days later they called me for final round it was with their director, Interaction was very rude, He was rapidly asking question from web service development and it's optimization like why we use authentication key in web service why Facebook returns access token and authentication token & alternative of these things, If you don't know any answer from these irrelevant questions he will say what you have done in your past professional carrier and pretending that he is the only one who knows better. P.S. they will not give you any intimation about selection or rejection.
