I'm not sure if it was the MH problem--all I can remember for sure was that it was a probability problem that was simple to state and the immediately obvious answer was wrong--but I have a similar story. Except I blew the problem and didn't get the job.

It was 1982. A small company from the Pacific Northwest called Microsoft sent some engineers down to recruit at Caltech. I was a senior that year, and interviewed with them. They asked me their probability problem, I got it wrong, and did not receive an offer.

I've occasionally wondered how different things would have been had I got it right, and so maybe got an offer, and accepted [1]. I think pretty much every engineer that started at Microsoft around that time and stuck with it (which I almost certainly would have done) ended up quite well off.

I've also wondered if any of the engineers that interviewed me are people whose names I would now recognize.

[1] It was not at all certain I would have accepted. I was more interested in bigger machines than the microprocessors MS was focused on, and also had a strong preference for staying in the Los Angeles area.

...in the alt reality you readily passed the interview and accepted the offer. MS tanked, DIGITAL pivoted into PC market and dominated it. At some point alt-you made this post on alt-HN.

We just hope to be certain about the present moment.
