Pluspunten
At the local level it's small, easy to fit in. The software systems, except for a few, are easy to use and help complete the job. Mid-tier is challenging and there's an awful lot to learn. If you put your head down and work you'll probably do pretty well.
Minpunten
Despite the fact that the firm has been around for 80+ years, the name is not well-recognized by either potential clients or potential employees making networking and recruiting difficult. There's an "every man for himself" type of culture throughout, senior to senior, manager to manager, partner to partner, but especially across business lines. So much so, that I've even heard one partner in one business line refer to others in another business line as "competition". Most business lines don't even know the names of the other employees across business lines and have no clue about what they do. Probably typical of all mid-tier firms, there's an overall sense that the firm just follows the lead of the Big 4.
