I did it over 4 weeks. I have two kids, so I spent about 1-2 hours per day. I usually did some reading or a couple leetcode problems in the morning before starting work, and a couple in the evening. Honestly, once you do about 20-30 problems, they start to feel the same. I found that if I treated each problem like an interview and slowly walked through a solution (versus just diving into code and mashing Compile over and over until I get it), the problem ends up being easier.

OK, so taking the usual programmer's working hours then add 10 hours a week to that. That's some opportunity cost there, just to be able to jump through a hoop that has little to no bearing on a real world programming career past the intern/junior developer level.
