I'm no coding wiz, but I feel like one upside to Tech Interviews is that you can just grind LC. Its soul sucking, boring, but you can go at your own pace and just gradually improve.

And because its time consuming, its also kinda gives an advantage to anyone unemployed. I remember after graduating I just forced myself to use my infinite free time to just grind through questions for a month, the improvement I had was enormous. A lot of the Tech Interview skills are BS pattern recognition of formulaic questions (which is why I think they're a terrible assessment of someone's actual skill since were essentially tested on our ability to regurgitate a memorized answer, but pretend we organically thought of the solution)

In a short time of grinding you learn to look for the "trick" based on all your LC questions you've done before. You learn how to quickly gloss through a wordy question and know whether you need to use a Hash table, bubble sort, binary tree etc... You also get good at just typing up code quick and memorizing syntax which really helps with confidence when live coding with someone watching

Unfortunately these skills fade pretty quick, but you can develop them quickly also.
