The author has been working as a developer for 15 years, and claims very strong technical skills. Why are they learning/re-learning Python, C++, SQL, C#, college math? Nobody will be fooled by that; at 15 YoE they will be evaluated on what they have done over a career, not over the last month.
> it's all about how much time you can spend on Leetcode.
The author is playing a game built for new grads. Here's a secret, speaking as an (ex) Facebook interviewer:
Facebook's hiring pipeline is optimized for new grads, but its hiring needs are senior engineers. They know this, but you can't build a high-volume interview pipeline for senior engineers: there's not enough of them, their skill set is too varied. So Facebook is kind of at a loss, but in general if you have 15 YoE and can show you're good, they want to hire you. In particular they'll try to find deep domain experts ("pirates", their term) to evaluate you.
So be prepared to demonstrate basic competence in coding, and also some deep expertise. T-shaped engineers, as they say.
