You might have one or two people in the room interviewing you. But I only had one person interviewing me. It is a series of questions that you could be asked during the interview. There is a book ok questions that the interviewer can choose from the topic that he/or is on.

I went in for interview with company and everything seemed to have went well. I was nervous but they made me feel comfortable. After settling in, I found that they were very welcoming and it went smoothly
