You may be right.
The companies I was CXO of created some pretty impressive intellectual property (deep tech; which I coded the v1.0+ for personally) and two books (major tech publisher not self-published). You're probably running code I wrote on your machine if you are on a Mac or Linux. Can't say much more without doxing my throw away account.
But I'm not sure any of those things would come across well on a resume, unfortunately.
> Finally, you're going for Engineering Manager, I think you shouldn't need to do leetcode. I think most FAANGs etc are going to ask for code reviewing interviews or the like, not have you actually doing algorithmic puzzles.
Interesting, I've heard that opposite. Good feedback.
> You do want to practice system design interviews.
Good idea. What do you think the best way to go about that is?
