Waited for half an hour after the scheduled time. And it was of one round technical interview.

It was Saturday and every one in office were working. Seemed scary about work life balance in this company. When checked about why whole office is working on Saturday, they told its common that they work on Saturday.

The interviewer was in hurry and he asked some questions those are familiar to him or which they use and if you haven't answered them then he came to a decision that you haven't worked at all in that technology. Just one or two question can't tell that you are worked or not.. It seemed like arrogant behavior. Doesn't know how to treat job seekers.

Program using async, await, Task, what are extension methods, etc.
