Perception Sales & Marketing interview questions

Short interview with one director. Didn't give me much background on the job or the company. Felt as though they were hiding things until they decided if they would hire me like who the clients are they work with. Interviewer was really scruffy and didnt look like a company boss. Wearing trainers and jumper and eating while we talked. Looked really shocked at everything i said as though i wasnt being truthful?
