Pros
Probably the best thing about Deloitte is the smart and talented people you get to work with on a day-to-day basis. The experiences you gain also benefit you in your later career, but are dependent on the projects that you are staffed on. Coming in as a junior resources allows you to try different aspects of consulting - something that you might not have been able to at another company.
Cons
Working at Deloitte is always about building your "brand" and constantly promoting yourself. As people are probably well aware, while the firm tries to promote the never-achieving "work-life-balance", I have yet to meet someone who has made it work. As part of building your brand, extra work is required to be spent outside of normal project work to help out on proposals, building firm eminence, contributing to the firm. Unfortunately, it's hard to get noticed, respected, and rewarded (i.e. financially, recognized), unless you participate in these extra activities.
Advice to Senior Management
Recognize those who deliver high quality of work as much as those who sell the work.
