Very easy-just do a simulation test much like the work you would have on the job then interview with HR the same week. Very easy questions they give you. If you have direct experience it helps a lot!

Does testing to make sure you are capable of sorting the documents according to instruction. Gives you a list of instructions, almost exactly as you would receive from a client, a stack of random documents (medical, legal, etc.) and times you while you sort them. Not very challenging however. Asks basic questions regarding past employment, education, etc. No questions that would be considered out of the ordinary.

I was first interviewed by a human resource person and then a supervisor. They explained the hours and the basic job skills required. They also said piece rate was being implemented in the future.
