I can only speak for software engineering: Hiring is extremely difficult and time intensive. I have a ~10% hire rate in over 500 industry interviews conducted.

I can only speak for software engineering: Hiring is extremely difficult and time intensive. I have a ~10% hire rate in over 500 industry interviews conducted. These were at large tech companies so they included 5+ people spending 3+ hours each. It’s not worth the time to fabricate head count to begin hiring, then fire a qualified person. We assume Amazon is cutthroat and grades on delivery. Imagine doing this sham while doing your normal job.
