My way of thinking differs by saying if from my individuals perspective I experience the perfect coin (quantum particle) to flip tales a million times in a row there must be a highly likelihood that many worlds indeed exist since I died in the ones it said heads.
It doesn't make that highly likely, though. It's about equally likely that there's a fairy controlling your coin flips. The experiment hasn't proven anything about the cause of the unlikely outcome. You've just measured that it happened and then declared that your preferred explanation is the reason.
I'm not sure that offline or alone coding tests are any better. A good coding interview should be about a lot more than just seeing if they produce well structured and optimal code. It's about seeing what kinds of questions they'll ask, what kind of alternatives and trade offs they'll consider, probing some of the decisions they make. All the stuff that goes into being a good SWE, which you can demonstrate even if you're having trouble coming up with the optimal solution to this particular problem.
