Pros
Interesting hands-on work environment - it's definitely a dream job for someone who wants to see the products they are providing support for being made in real-time. The company offers great benefits and has a very strong tuition reimbursement package to utilize. The relaxed dress code for non-managerial staff is a plus.
Cons
Pratt is far too big to feel like you have the opportunity to advance quickly. The company is inherently bureaucratic and thus feels very far behind the times... it's far from nimble. Management is very much focused on politics - an issue that is noticed organization-wide and frowned upon by individual contributors. Overall there is very little recognition given for good work, and there is an overwhelming mood induced by feeling easily-replaceable and under-utilized.
