The best aspect was that interns were not treated any differently than new full-time hires. The company invested a lot of time and money into the interns even though we were only there for 10 weeks. Within 10 weeks I had a very good understanding of what it would be like to work their full-time. The pay is also very competitive for a summer internship.
For a large portion of my internship, I was on a very busy project that involved long hours. I understood that consistent long hours were not the norm at the company (and find as a full-time employee that it is not the norm), but it would have been nice to have more time to explore a new city.
Advice to Potential Interns
Cornerstone is a fantastic place to work. The people are top notch in respect to both intellect and people that you want to be around. The work is interesting and diverse. The internship is the perfect way to determine if Cornerstone (and litigation consulting) is a good fit for you.
Advice to Management
Cornerstone actively tries to foster a work environment that people enjoy. I would say keep doing what you are doing.
