Join for a year, get the name on your resume and then run for your life.
Pros
It's a good place to start out. The people are young and generally friendly. It's great if you are moving to a new city, you immediately have a network. Lot's of the new hires are not that bright, but are ambitious. Almost none want to be here long term, so if you actually show good work ethic and enthusiasm you get great exposure and you will gain experience fast.
Cons
It all goes downhill after the initial excitement runs out. Everyone is looking for ways to get out. The salary is survival-level, the hours are definitely not justifiable by the pay. The culture is that the work is never off, you are on call 24/7. People get upset if you are not checking your email every 2 minutes. Everyone expects a response withing minutes. You have zero social and personal life. People are extremely bitter and miserable - most say that they will put up with it if the pay was not this bad. Job security is a thing of the past too, recent layoffs show it. Deloitte is a very transitional place, they expect to use you and that you leave. There is zero expectations that you will be there long term. The moto "people first" is a joke - politics are a lot more important that people. Don't expect Deloitte to help or assist you in any way if you need something. While most client service management and partners are actually nice and accommodations - the support staff (HR, etc.) are extraordinarily incompetent. They will make every effort to derail what you are trying to do and will never support you. The bureaucracy is really set up against people's best interest and is impossible to battle. Also, forget about quick advancement - 3 years for senior, 3-4 more for manager, 3-4-5 more for senior manager, then another 4-5 for partner. Making partner in less that 10 years is a thing of the past, now you will wait 15-20.
