Two phone calls occurred.

The first was a general icebreaker. I have been an entrepreneur throughout my career until now, so the call was basically to judge whether I could adjust to working under someone else.

The second phone call was to know me better. There were no technical questions asked until this point. Huge expectations were being built up on their side simply by judging my resume, so they assumed I knew all the technology there was to know.

The third round was via Skype. Still no technical questions were asked to probe my in-depth knowledge. So, in short, an expectation mismatch was on the cards.

I was not asked any tech questions. It was simply about what my projects were about and so on. I was only giving my part; there were no counter-questions from their side.
