Pros
Its a large, relatively stable company. You won't be fired, even if you are not that productive or useful. Parts of the company are real moneymakers, so even with constant poor decisions the company will stay afloat. You can find great coworkers and the occasional good performer that gets it.
Cons
Wow. Where to start. HealthCare - TU now dabbles in healthcare, but has very limited grasp of the market. Their decisions and focuses are confusing and almost mind numbing. If you have a good grasp of the current marketplace, correct pricing, correct expectations, and what is important, then prepare to be frustrated. Acquisitions - if they buy you, get ready to grind to a halt with red tape, policies and procedures, and generally messing up your stuff. Client satisfaction will go down, prices will go up, and you will have to constantly explain how your stuff (used to) work. Outsourcing - sending client calls to India, and outsourcing development...yes, these are good strategies. Limited upward mobility. If you don't play politics and fluff the right way, you're not moving up. You won't even get interviewed or a courtesy chat if you apply. The job can sit open for months, almost a year - and you won't hear anything. Management - lots of consulting background types. Not the dive in, get your hands dirty, understand things consultant (do those exist?). Everyone's been around some consulting company for a decade or so, and this is their chance to cash in and sit back. So you will not get active minds or hard workers at this level. Input - not appreciated. Try to use your expertise, effect some improvement or better direction, or even try to stave off the impending disasters and client atrophy - and you will be labeled as a negative presence offering too much resistance. Take your resistance somewhere else - and make more money in a better environment! Win-win! Overall TU is something of a throwback...their outlook is some combination of decades from the 50s to the 90s. Bonus is limited to management or above. Pay rate for senior management is huge, but anything lower will be sub-par. Everything is about process and red tape. Innovation is not on the agenda. Other companies will be faster, smarter, and better - they will just buy the cheapest one. Truly a thrilling, fulfilling atmosphere. If you have the consulting background and want a fluffy job with lots of flying around and not much actual work, TU may work out well for you. If you want to be on the cutting edge, or within 100 miles of it....if you like being productive...if you want to have input and form a good connection...then TU is not for you.
