Need some help with an interview I am going to

I have an interview with a recruiter for a biotech company on Monday. This is my first interview, so I don’t really know what to expect.

I want to know about 3 things-

1. What did you respond with when they said “tell me about yourself?”

2. Which interview questions have you been asked before and what were your responses? I’m especially wondering what to say when they say “why should we hire you?”

3. Which questions did you ask when they said “do you have any questions?”

Also, during the interview, where should I place my portfolio? In my lap?

Thanks.

Jam it back in, in the dark.
