I was selected for the phone screen, which went well, and then selected for the interview loop. However, because I was not exactly an industry hire, I was dropped from the process.

I was still completing my graduate studies at the time and was set to graduate. In my mind, I was looking for a full-time opportunity, but unfortunately, I could not move forward as they were looking for someone with more experience.

One of the questions I was asked during the phone screen was to describe the difference between convolution in the time domain and the frequency domain.
