Wait to fully vest Oscar options or take FAANG job now?

Wondering what the best strategy is for me financially in short / long term. Have 40,000 options with Oscar that will fully vest after 4 years, grant price of $3.50. Currently only half vested. Never had options before for a company that I felt was actually doing a good job, so I'm pretty positive / bullish. But also unsure of what kind of money the 40k options could turn into. Starting to chat with FAANG companies recently, and while I would love to work at one of them like Google or Facebook, I'm unsure if its worth it leave right now pre-IPO and with half unvested options to work for a FAANG (Hypothetically speaking, if I were to get an offer). Since this is all new to me, I'm just curious what others would do in my situation. Would you hang tight, fully vest and see where the stock goes in 2 years? Or if you were offered a solid L5/IC5 offer at Google or Facebook, would you take that instead? Cheers! TC Base: $190k Bonus: 15% Stock: 40,000 options / 4 years @ $3.50 grant
