<p>Email?
Handwritten note?
Someone also suggested to me sending a basket of goodies to the firm...candy, fruit, whatever else. They said it would make me stand out among students and show enthusiasm and appreciation. Would that be too much?</p>
<p>I don't want to seem like a complete brown noser. I was sincere the entire visit and do honestly just want to show my appreciation and how much I liked the firm, I just don't know what's the best way to do that.</p>
