I had a Skype interview which lasted for almost 60 minutes. There were three interviewers, and they gave me control of their screen. As the interview started, one of them gave me an overview of the work being done at the company for the position I was interviewing for. This explanation was highly technical; I could only grasp half of the terms. After that, they opened a presentation. I thought they would be explaining something in more detail, but there were questions within the presentation, and they started asking them. Overall, the process was smooth, and the conversations were healthy.

Write a C code to find the number of bits between two integers.

In the second question, they made me understand a networking process and asked a question on a similar process. This was totally unrelated to my background or current field, which I think was pretty odd for them to ask.
