It was really difficult to understand the interviewer. I asked him to call me back, but the line didn't improve. I asked him multiple times to repeat the questions, but it got to the point that I was pretty much guessing the question based on a few words I could make out. On reflection, perhaps I should have just stopped the call early. I messaged the recruiter after, but received no response. Besides it being incredibly difficult to understand the interviewer, he seemed more interested in getting info how to do his job, rather than actually finding out what I was capable of. Apparently, he has a hard time convincing the sales team to market their video product, because they see no value in it.
