Pros: The pay is good, the people are smart, and the snacks are free. Work is generally interesting, and a good deal of flexibility is given to make your own hours and choose a project that is engaging for you.

Cons: Developers often have to support legacy software that has no chance of ever being replaced. The company has some really proprietary practices, architectures, etc., that do not translate into building your programming skills in the world at large. This often makes it tough to transition out of Bloomberg to another company.

Pros: Free snacks and soft drinks. Pay is good. The company really pays a lot of attention to the internship program. The people working there are smart.

Cons: Technology is amazingly old. Do you know Comdb? Managers don't care about your feelings as long as you get the work done, regardless of how you achieved it. For an intern, whether you can get a full-time job offer is independent of how your work was during the summer, even if you work hard and your mentor and manager like you.

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.
