Im working in a mid-tier law firm in the city that does a bit of everything, I guess there are some differences (which granted, you should really expect anyway) but also some similarities.
Solicitors still do a lot of legal research, Im often at the law society library fetching copies of cases and what not. And the practical stuff like client interviewing is very similar to what you learn at uni.
On the other hand I guess when you get into the practical environment theres a lot more focus on the human side--at law school you are focussing on what the law says and how to apply it whereas in my experience working in the firm Im at, theres more of a focus on making sure they client ends up happy.
