Adcuda interview questions

I was scheduled for an interview there and the person who was supposed to be handling the interview couldn't attend. I received no phone call or communication of any kind. I arrived at the agreed-upon time and was told by someone that this person wasn't in. What's more is that the other two who were scheduled to be in on the interview were completely oblivious to the time and weren't prepared so I was made to wait until they could prepare. Very unprofessional. And, of course, there was no response to my thank-you letter by the person who didn't show up. No apology, nothing. I'm glad I didn't end up working there.
