The best aspect is that interns have direct impact. I got to prepare whole returns that went directly to the client after being reviewed by another staff and a partner. Being part of that team delivering such a tangible service is a very rewarding feeling.
I wish the internship could have lasted longer, but I realize that it couldn't start any earlier without excluding some colleges' students.
Advice to Potential Interns
The people at Moss Adams really are as great as the people you meet on campus. Also, don't shy away from the smaller size of the firm because the breadth of experience you will get is so much greater at first and you will get to decide where your career goes, which will be much more valuable 10 years into your career because you will be personally invested in and passionate about your work.
