I used to work in a client facing role for enterprise software before I got into programming. The ability to stay cool and override nerves with sheer adrenaline that I developed by attending high pressure client meetings is 1000x more helpful to me in technical interviews than any leetcode practice problems. If you have the basic technical knowledge and problem solving skills then 99% of the interview is just staying calm enough to use them properly without coming off like a nervous mess. Much easier said than done, I know.
