Serious question. 500k job openings is a lot. Where do go to find these job listings? Are they still spread out across lots of job listings sites like Monster, etc.? Are they doing a total of all listings across those sites? Is there a defacto site that everyone uses now? Just wondering if I’m doing something wrong.
