The job market has collapsed. You need to know someboody. https://en.wikipedia.org/wiki/The_Market_for_Lemons
There is also insufficient information going the other way. Unlike buying a car, there is more to the buyer's side than just money. There is the work environment, how well employees are treated, the probability of future raises, probability the company will lay you off or cut pay or force you to relocate in the future, etc. And that assymetry impacts the market as well. For example a company might be a really great place to work, and that would compensate for a lower salary, but the prospective employee doesn't know that.
