If you assume some correlation, even imperfect, between SWE effectiveness and interview performance, the least effective SWEs are likely to both be looking for work more often and require more interviews per successful job search, so will be way over-represented in the “who applies to interview” pool.

Joel Spolsky said it well: “A lot of companies think they're hiring the top 1 percent because they get 100 resumés for every open position. They're kidding themselves. When you fill an opening, think about what happens to the 99 people you turn away. They don't give up and go into plumbing. They apply for another job. There's a floating population of applicants in your industry that apply for nearly every opening posted online, even though many of them are qualified for virtually none of these positions.“
