PatSnap Sales Representative interview questions

Firstly after getting a confirmed email for the interview, the HR didn't show up at the time of the interview. I took 1 hr off my current job to appear for the interview. After sending 2 emails, the HR didn't get back to me. I tried calling the Toronto office nearly 10 times, but no one received my call. The company seems to be suspicious to me after this horrific incident. After a week, I again send an email to HR and another email confirmation for the interview. I appeared for it, but in Canada, the company usually doesn't ask for your previous annual salary, average monthly sales, but the HR did. It sounds to me like a fake company. It looked like the company already had a candidate and wasted my time.

I applied online - very brief telephone interview (only 5 mins) - got invited to a face to face interview. It was unorganised, he was asking irrelevant questions, I think he was drunk, no structure, a complete nutter - questions asked were very basic .
