I have engineering degrees and was a product manger for a long time. My jobs over the last 20 years have almost nothing to do with anything specific I learned in an unrelated field of engineering--though learning to think/problem solving/etc. may well be. And far more to the fact that I've written for newspapers and have increasingly spoken and written on tech matters over the years.
It is distressing how much emphasis is placed on mastering toy Leetcode-style algorithm problems in software career-building (for obvious reasons - they're used in interviews) and how comparatively little we emphasize the skills like writing and public speaking that actually count for some of the most successful tech folks.
