Late Input

So let's see. Your choices are:

#1. Continue on to accept the unpaid internship at an architecture firm; full time
#2. Wait for potential paid internship; full time

Do you know how flexible each is? Or at least the first one? Because what if they both want you to work from 8-5pm.

Since it's just for the summer, taking both sounds like a really good idea. It may be hard but it'll pay off in the long run or at least until you get a feel for both places and decide how you like it, etc.

My advice is to see how flexible both places are. If they are, take both.
