Question about possible level at Fb/G

7 years of experience, almost two years at Intel, then co-founded startup and successfully shipped a few products (mobile games) in last 4 years. Being product/lead dev/ceo at the same time. Got seed funding, but was unable to get traction unfortunatelly. Now I consider applying for Swe at Faang, what level should I expect to be graded provided on-site is cracked? Are they going to value startup experience as co-founder in any way? Is it going to be just L4 as they don’t care about previous non-faang experience? Thanks
