Staffing Solutions interview questions

I applied online to a couple of different positions and was asked to set an interview time online at that time. Set the time and called immediately to confirm. Was told the positions were still available. Showed up at appropriate time, given a typing test and test for Office Word. Receptionist then contacted person to give interview who told her she did her own scheduling and would not be seeing me that day but would review testing and call to schedule interview. Felt like I totally wasted my time and theirs
