I'd love to, as I'm really tired of my current employer, and they're definitely taking advantage of me, but I resolved to never waste my time with leetcode garbage again... which means I either stay where I'm at, or exit the industry entirely.
If so, I bet they can help you get past the coding tests.
An alternative is to grow your connections by going to meetups or something similar (I know, more unpaid labor! But it will pay off.) After 2-3 months, you should know the regulars and can have the same conversation with them. For bonus points, offer to help out--meetups I've encountered are usually looking for some kind of help, whether that be running a meeting, finding sponsors, helping speakers or something else (even, in the before times, setup and teardown of chairs/meeting space).
Please don't get me wrong: if it was just a few days of practicing, I'd just get it over with and do it. But realistically, with the leetcode arms-race that's gone on for the past few years, where you're expected to solve multiple hard-level problems back-to-back, with no assistance, and as quickly as possible (ie: under 30 minutes), I'm staring down the barrel of probably 3+ months of full-time grinding to memorize as much of them as possible.
Just not worth it. I'm terribly depressed as it is already, and that would just make it much worse.
maybe after a while it would be second nature once a real opportunity presented itself?
