How are you getting paid more than Google if they're a private company? Are they paying $400k liquid? Monopoly money stocks cannot be factored in as real liquid comp unless you can actually liquidate it. If this is a known company to IPO in a year or something then maybe you can make an argument but... I don't think they're comparable, IMO.
Yes, liquid comp (salary+bonus) exceeds my total Google comp (salary+bonus+equity). I should qualify this by saying I left Google as an L4 SWE and I'm starting at this company as an engineering manager, so that factors in. But FWIW I got an offer for a tech lead position at another all-remote company, and it matched my Google total comp with just salary+bonus as well.
