I see so many people talking about how irrelevant algorithm skills are for real world coding, and lots of allegations of age discrimination. I see the validity of both points, and I’m sure they are true. But people, please, some perspective. The author spent a couple of months studying and practicing material in their spare time and got offers from top companies in the comfortable 6 figures. That happens in no other industry, ever. Look at what lawyers, structural engineers, accountants, and most especially architects ... not to mention the obvious one: doctors, go through to be qualified to make good money. The author presumably graduated with a bs, worked for pay for 2.5 years, did some online learning, and makes a great living? A doctor would still be in (very expensive) school. I suspect there’s an element of IQ-ish testing with these puzzles and it sucks if your brain doesn’t work that way and you are permanently excluded as a result of that. But if you have the capacity but can’t be bothered to learn a bunch of material over a fairly short time frame to handle an interview, why should these companies want you? You obviously just don’t care that much, because the investment is tiny.
