The interview itself was quite easy. They'll ask you about why you chose fidelity and why you're interested in finance. My advice is to do some research about the company and try to come up with ways to prove why you would be an asset to the organization. Also, be sure to look professional for the interview as they take that very seriously. Other than that, there should be no problem. They make you feel welcomed and they'll treat you like family. I highly recommend it!
