Black Box Security (CA) interview questions

I applied online, though LinkedIn, as it sounded like an interesting position that I would be able to transfer some of my previous background. According to LinkedIn my application was viewed pretty quickly, although that is not always an indicator of anything. I received two phone calls in rapid succession from a number that I reverse Googled back to Black Box. There was no message and no follow-up or message in my email. I have no idea if they were actually interested or not, but this appears to be very poor recruiting if so.
