Help with interview

I have an interview for magento frontend development and even though I have worked on it before I always worked in a team of 1 so I had to learn everything myself, now I have an interview with a company I am looking to impress, any resources or pointers which I can go through to help prepare myself for the interview?

The person interviewing is a certified magento dev whereas I am not and it is kind of intimidating to be honest.
