If you’re looking for a job, Manpower is a good choice, but I can only say that you need to work with the right manager.
If you’re an employee looking for a job through Manpower, my honest advice is to make sure you find the right consultant. The consultants vary considerably in quality, so I recommend working with the right one. Before the interview, you can ask the consultant plenty of questions. If they keep talking in circles, please ask to switch consultants.
