Squint/Opera Post Production Assistant interview questions

I applied for the job and suddenly out of nowhere, I received a call from HR. I was not in the right environment to talk with anyone, but they insisted on asking a few questions, which was essentially a short interview. I asked if we could schedule another phone call and they never got back to me. This method of "surprise calling" has to come to an end, and it is not a good look for the company.
