But did you get any of those jobs? I wouldn't call being invited to the next round successful if you don't get the job. In fact it's a loss, more lost time for the candidate.
Yeah seriously - "rounds" don't mean anything unless they publish numbers, and even then it's sketchy. You need to be able to verify that they're actually there to shrink the pool, not just provide the impression of it. Take-homes are free for the company to issue.
