Advice
Don't be afraid to check out small companies! The summer before I worked at a Fortune 500 company, and I wasn't sure what it would be like to transition to a company of 50 people. I ended up loving it, and I formed really great connections with my coworkers, mentors, and bosses. I would also advise people to take internships with companies you can see yourself working full-time for, because if you do well at your internship that company may offer you a full-time position.
