I think this leads to a lot of false negatives when interviewing. but if you are applying you obviously want to increase your chances of succeeding so, you have to know how to 'play the game'.
My recommendation to you would be: 1. spend a lot of time preparing for these tech interviews. Study how they are structured. There is a lot of material online (blog posts) as well as books documenting what it takes to succeed. 2. there are some people that do paid courses on "how to interview at FAANG style companies". they may be worth depending on the upside. Note that not all companies have those types of interviews but if you are aiming for them it makes sense to prepare the best you can.
