You're right, I probably took it the wrong way.
Clearly, in a 8-10 week period you wont see all there is to see in a service line. In a 2 year period you might not get a complete picture of your service line. You might work on a couple of engagements’ in detail. Or you could work on odd bits and pieces. Generally, at the time of the year when you are hired, there is not that much work to do, so you really have to scrap for it. Most of the time you are getting work from grads - why would they give you anything remotely good to do, when they haven't had that much experience yet and want to do the interesting work.
What will happen is this. You will go in there keen to do something productive. You will then be given the most unproductive work, which usually some support staff would do, or that wouldn't be done. You will then have a choice, try and do a good job of it (i.e. don't get bogged down by that crap) and network your way to some good work; or do what most vacationers do and go to all the social events, send around 200 emails a day, and pick up your pay cheque at the end of the week.
You will realise that you are at the bottom of the accounting food chain. You will also learn that offices are filled with unproductive and unnecessary politics that people will try to drag you into. Steer clear of the people who try to involve you in this. Who are we kidding, you cannot avoid the politics, and it shows how unprofessional people are when they try to coerce a vacationer to join their power plays.
You will come to the realisation that if you are to do possibly some of the most mundane work that you should at least get paid well for it. You will know you're not getting paid well for it.
You will then be given an offer that is designed to trap you. Its aim is to secure you into a job so that you do not look at what else is out there. You should look at what other jobs there are. I would go to an accounting firm last, even a Big 4 one.
Oh and on another note, most ridiculous thing I have ever seen is a vacationer having a "restraint of trade" clause for when they leave in their contract. Even worse is that they have to sign the restraint of trade clause on three different papers, and then twice when they leave.
