Interviews for web development positions are usually based on a series of questions and some discussion of your past work.
These resources have lists of questions you will often hear in interviews. Study these questions and write out an answer for each one before the interview so you can be ready to recite your answer in the interview.

When the interviewer discusses your past experience and projects you must be honest. You will not be able to hide the fact that you are starting your career as a web developer, but you can emphasize the positives you can offer their firm.
All you have to worry about is getting hired. Do not ever talk yourself out of applying for any job.
If a company is willing to hire you they will give you enough time after you start to learn what you need to know to work there.
Remember, even a bad interview gives you good experience for future interviews.
