I'll second the opinion of having your contracts reviewed, but will curb some expectations: most contracts (NDAs, employment agreements, home contracts etc) are fairly standard. There may be some small points to negotiate if they are off-market, but you had better have the leverage to negotiate.

If you get a SDE offer from Google then sure, there is probably no room for changes other than some adjustment to salary and stock. If you are employee #10 at a startup (which is what this video is about), everything is negotiable, and you are shooting yourself in the foot if you don't go over your contract with a magnifying glass and professional help.

That's a valid thing to keep in mind with big corporations. But if you're joining as employee number 5, and they claim they aren't willing to negotiate on something you dislike in the contract because it's "standard", you should leave the interview.

It's exactly what they're talking about in the linked video - you think you're joining as a valued partner, but you're clearly just a cog in the wheel.
