Applied online. If I remember correctly, I received an email to schedule an interview. That only took a couple days. Then I came in and did a series of tests, eg. Excel. It wasn't until I was in the interview, that I discovered it was for a full-time permanent position, when I clearly stated I was only looking for temp jobs as I would be leaving the country soon. So I was called in to interview a separate time with someone for temp jobs. The interview was pretty basic, no tough questions. I received a job opportunity shortly after. They don't tell you the company until after you accept the offer. Makes sense so that you don't go apply to the company yourself.
Keep in mind, anywhere you work through the temp agency, you can't work there for at least a year. Otherwise they will take a commission on it.
