Maybe. So after you complete on-site interviews you are reviewed by a hiring committee which goes over the scores in each stage of the process, and decide whether you should move on to project matching. Typically passing hiring committee means you've made it. However this wasn't the case for me in Spring 2017 where after on-sites they told me they would not extend an offer but could not explain why. Oddly, a year later I reapplied and got the job without any further technical interviews (but a recommendation might have factored into this). I found this pretty bizarre and hiring for diversity might be a plausible explanation considering I'm a white male, though what's inconsistent with the story is that they certainly didn't purge my application. They were hounding me with emails to reapply ever since they turned me down. There are probably a lot of boring reasons this could've happened as well. It's probably boring.
