Still have trouble seeing how this comes out ahead. Say you're at Google or Microsoft where it's 50% up to contribution limit, and you get $10K in match. That puts you down $12.8K vs. your hypothetical. If you're getting paid $45K more at the FANG, you pay 35% taxes on it, which puts you $30K ahead after-tax, and then you invest that in an after-tax 401k (or even just a normal investment account), after which you're in exactly the same situation but about $17K ahead each year.

Also, FAANG will negotiate offers against fringe benefits. They won't cut you a custom 401K deal, but they will beat any offer by 20%+ and include the post-tax cash equivalent of better retirement packages in that beat. If you ask for it and if they want you badly enough.

Assuming you can get a gross offer that matches net, having the money in post-tax accounts is better because the tax rate on the 401K at withdrawal will likely be higher than the 15% capital gains rate.
