Pros: Awesome location, snacks, usually interesting work, and good hours. The employees seem very content and taken care of. The full-timers were very welcoming to the interns, inviting us to play frisbee after work. The work-life balance was good -- people normally left around 6 pm to do that sort of thing. The interns had a week of training which also allowed us to socialize, and the intern class ended up pretty close and brave.

Cons: The codebase is largely old and kludgy (like any 30+ year old company). They spent a week teaching the interns how to use their proprietary stack, though, and it's pretty effective at what it does.

Pros: Many excellent trainings, both on Finance and Programming. The intern program is nice, and I learned a lot from my teammates.

Cons: The work can be boring if you have been there for many years. A messy codebase makes it hard to change and maintain.

Pros: Very good hours. Nice and helpful team members. My team members are intense during the working hours, but they all keep an 8-hour working schedule. The culture is very nice and welcoming. Everyone is very willing to help. Great transparency. Flat structure. Mike Bloomberg came to talk to all the interns. You feel that they are really encouraging new, innovative ideas, being bold, and asking questions. A lot of very fun intern events (in fact, too many that I sometimes don't have enough time to work XD). Not hard to get a return offer. I'm not sure why some interns said it's hard, but at least it's not hard for developer interns. The summer picnic is really AWESOME and a lot of fun. Very good hourly wage for interns too.

Cons: If you don't like New York, the location might be a con. It's also not as geeky as Google or other big tech firms. But everyone is very nice and hardworking. And everyone can easily fit in since people are very diverse there. No free lunch, but there's free dinner if you stay late.
