Even minimum wage jobs are hard to get in any economy. Interviews are impossible hurdles to get over and I don't see the necessity of it, at least not in the way it's traditionally conducted. For instance, almost 10 years ago, I've interviewed with 20+ companies over a period of 2 years before getting a single offer. I stayed with that company (Sam's Club) for 5.5 years. If any of these 20 something companies offered me a job, I woulda had the same outcome.

When I searched for a 2nd job in addition to the one I had, I interviewed with 10 additional companies and received zero offers. I guess it's normal for people to get that many interviews and receive only a couple offers out of it. Or am I wrong? What's normal then?

I'm currently at McDonald's and looking for a 2nd job. I've had one interview and no offer. I've ran out of places to apply because most of the companies that ever interviewed me would not consider me the 2nd time.
