My interviewer gave me a live coding task and then completely shut down any attempts of me solving it. I actually bailed and we closed the interview earlier because I could not come up with a solution. After I looked up the problem, I realized I was completely correct, not once, but twice. The solution I proposed initially was the correct implementation, but as my interviewer instantly shut me down and told me it's not the proper way to approach it, I scrambled for another solution. This solution was absolutely correct (and relatively efficient), confirmed by a simple Google search. Again, he told me instantly that it is not correct, and that I am not seeing "his" correct solution. This left me with a bitter taste. Also it was casually mentioned at one point that this is not a 9-5 company, that they want ambitious people who are there to get it. You want overworked monkeys who can only think in a singular, defined way.
