Sorry for not clarifying about verification versus speculation. I talked to the candidate on the phone at the end of the process. The candidate felt like we had moved too quickly and had remaining questions. The last interview would have answered those questions, but no doubt, that’s partially speculative.
"Great now, we would really like to see an example of your code".
"Well all my stuff at work is in house, and contains some sensitive information. I have started a small side project recently, but you will have to understand that it is not finished. Have you got a bitbucket account?"
"Great, now we would like you do dedicate a bit of time to set up a simple flask API...."
"I have sent you an example for real work I have done, I don't think it is really necessary for me to set up a project using two technologies I am not familar with..."
The guy kept of framing it as if I was causing a problem. I said I would do it for the local freelance rate, but that seemed to go unnoticed as I was asked for a solution to my reluctance to do the test.

Not sure how I was supposed to solve a problem in 45 mins that had been haunting them for a year.
Yes, interview me for fit (on both sides), but subjecting me to an endless barrage of technical interviews where you ask me questions I've heard dozens of times before is much more likely to get me to drop out of the process than subjecting me to not enough is. The article says they skipped "one of the final interviews" suggesting there were multiple already... And within one interview I can assess the skill level of the people interviewing me without having to attempt to intuit it based on how many of the "Microsoft questions" from the 80s they found on Google to ask potential candidates.
Are you sure the candidate was "spooked" because you didn't interview him or her that one final time? The article doesn't do a good job of explaining if that is speculation or verified feedback from the candidate. There are a billion and one reasons why someone might give you a pass.
