I landed my $bigtech work last year via a leetcode process but it was pretty lightweight and tasks were simple (I do frontend, maybe other positions have more difficult tasks). YMMV depending on company but don't assume leetcode = solving NP-hard problems.
Also pro tip: absolutely do a fake interview before with a friend before each step. You'll fail miserably and stress af, but it will give you point to reflect on and prepare for real one not to panic.
