I learned a lot about a corporate environment, debt in general, what employee lifestyles were like, and a lot on excel so really what was enjoyable about it was the fact that I learned so much.
What I wish was different
I wish it had been more fast paced and busier. I was given one main project but I definitely had a lot of free time I filled with general reading on investments.
Advice
Show up early, do your best, and definitely try every day to impress them and not stoop to the level of other people who are comfortable because its a relaxed environment.
