Express Employment Professionals interview questions

My interviewer was 40 minutes behind, so someone at the desk had me do skill tests (typing alpha-numeric, some simple Excel and Word exercises). When I was done, I was put back into the lobby to wait. 10 minutes later, a different person took me back to the skills test again for 5 minutes before he realized I'd already done it. Back to the lobby for 10 more minutes. Finally interviewed with my contact 45 minutes after our appt. Basic questions about work history, very surface questions, nothing situational. Then she asked me what my biggest weakness was (is this the 90s??) and I told her I had to be back at work (I lied).
