Very lengthy, but wasn't bad. You have to go through 2 rounds of interviews. The first is with the HR staff member, and then with the HR Staff, the Office Manager, and possibly a case manager. They are going to be paying attention to the amount of detail in your resume and have it marked up for errors, so you should probably have that fixed (life skill...). If it isn't you probably won't get a call back. It's an internship position so prior experience wasn't required, but having already worked in an office would be a huge plus for you.
