The culture - mostly young analysts/associates/managers within the office, very friendly, collegial atmosphere.
The work - very interesting, most cases involve large well-known companies, learned a lot about many industries.
The mentorship - assigned multiple mentors at varying levels of seniority.
Overall it was a great place to work. I was excited to come in every day.
Full-time employment opportunities were kept relatively secret; didn't know where I stood many a time. Though interns who got offers were told on the last day of the internship.
Advice to Potential Interns
Ask any and all questions. Ask for performance reviews from your managers and fellow analysts. 10 weeks flies by very quickly.
