>Who: Series B startup with ~$100 million in funding, me open-source developer

That $100 million isnt in your pocket. This isn't 100% reliable source of income. It might seem like alot but it's not established yet.

>In a meeting they explain how they were interested in using my open-source project and want to hire me so i could carry out a similar work for them

Sweet, i assume they want to use your code. Might try to be tricky and get you to sign your code away. Then fire you and keep the code base.

>Then they go on and explain i’d have to do 4 more meetings 1-2 hours each, including a leetcode-style tech interview

Kind of a red flag in my books. If they are coming to you, then it's the reverse. Like they should be offering you equity or something. I dunno. They need to win you over and bureaucracy isn't how to do that.

My code is GPL, lol

Like I dont know either way what's going on. There's tons of examples where an employer has you sign your rights away, then removes the GPL license and then starts publishing the code as proprietary.
