Pros
Some good people here, but there are everyone and quite honestly they didn't stack up to the Big 4 or boutique consulting firms I have worked for in the past. As with most big firms, there are opportunities to learn and network.
Cons
Short-term view of the world. As with most firms, they'll do everything to protect/benefit the partnership at all costs - if you're not one then you're on the chopping block at all times. They are bleeding cash due to horrendous audit revenues this year. Do a search for "Deepwater Horizon & McGladrey" - maybe clients are waking up. They are not a Big firm - they are an amalgamation of lots of little firms and their horrendous internal systems and processes show that. They constantly pay less than market rates - they reneged on a promised bonus for me and low-balled every person I hired for my team. Finally, their medical plan is just awful.
