Vantaggi
Learn the profession; interesting work, but not a lot of variety. Great junior people; eager to learn and willing to lend a hand. A few terrific senior partners; too bad I didn't work for them. Looks great on a resume when you go for the next job. I learned all I could about the particular area I worked in spite of the overwhelmingly bad management. Most of the people I worked with are long gone.
Svantaggi
I was treated like second class scum by my senior manager, who did nothing to help me advance my career. When asking a question to expand my knowledge and improve my performance I was called "stupid," I was derided for not already knowing the answer, and was told to "go look it up in a book and when you have the answer then come tell me." I had another direct female manager who came in late every morning, obviously hungover, slopping coffee all over herself, and would come to me and say "[my name] I'm not going to take this crap from you anymore" and other such pleasant greetings in front of all my co-workers. Never was I complimented on my work product or how hard I worked. Yet, when I finally left the company, there were 17 people at my going away luncheon, including several senior partners. But of course, the person who I had slaved for for over 7 years had a convenient excuse not to show up.
