Pros
TT is a company that truly provides excellent opportunities. There are few places that pay this much for so little work. As long as you can sit in your cube for more than 4 hours a day, you will be rewarded. Also, if you have any relevant experience in companies outside the industry, you will very likely be promoted. It only took 3 months of working at Google for our CEO to gain his position. So if you have been interning at Facebook, or LinkedIn, or Twitter you have a high chance of becoming a senior manager. The office space here is excellent! There is a brand new kitchen with a real bar (free beer!) and fridges full of snacks. The company spent lots of money on renovations (after firing 50% of workforce) for all employees to enjoy. Oh, and don't be worried about the non-compete rumors. You will be fine, as long as you don't work for another trading or software or service company.
Cons
Nothing I can think of. This company is great!
