It was a Skype interview and the questions were mostly based on my resume and a few general HR type questions. I was interviewed by one of the Principals of the company and overall it was a very good discussion. They were looking for a person with minimum 2 years experience and I did not have that and so, did not get an offer from them. The Principal, however, told me that my interview went on really well by writing an e-mail and explaining the reason.
