Manpower is the staffing company. They were very prompt about contacting me to send my resume to a potential client and then scheduling an interview with client. Took about 1 or 2 days to hear from them, and then scheduled interview for next week. When I interviewed with the client, I was interviewed by 2 people, the manager and system analyst (who had been taking over some of the accounting tasks). It took about 1 hour to 1.5 hrs. It was very casual, some joking around. They ask some soft skill questions (provided by company HR). I had brought my laptop so they asked to see some of my projects/writing samples. Was offered the job at the end of the interview, which I accepted. Went to Manpower the next day to fill out paperwork and do a drug screening.
Overall, I was impressed by Manpower's promptness and response rate. Most places don't even bother contacting you, because they might not need a replacement right away or they don't really have the time to weed through the applicants. However, with Manpower, it's their job to find the best employees for any job openings so they don't just sit on an application.
