Weirdest interview of my life. Interviewer didn't seem very prepared, he asked maybe 5 questions and then asked if I had any questions. Offered me the job without even telling me about benefits or giving a tour of the office. Seemed a little sketchy? or desperate?

The interview was very unprofessional and it was clear that the VP was not prepared. He asked about 3 questions then asked what I was looking for salary-wise. I feel like I barely spent any time there and found out nothing about the company. And same goes that I don't think he actually gained any information that wasn't already on my resume through the questions he asked. After how brief it was I still got an offer letter hours later. It was very unprofessional and ultimately felt like a waste of time on my part.
