Same can be said for the 'is the product of high quality' line. I don't think the first four iterations of my last product were of particularly high quality, but we were shipping things and it worked just enough to make users happy.
The one that stands out the most to me is the 'Would you be afraid to hire your smartest friends.' This is IMO the end-all gut check. If you wouldn't try to sell your best friend on leaving whatever they're doing to come join you, you don't believe in the company. If you don't believe in the company, find another one. There's plenty of work in SV.
It's also worth considering whether you would help find your replacement. If not wanting to invite your friends is a bad sign, what does it say if you wouldn't tell people you don't even know to work for the company?
I recommend this list, which includes this important warning sign:
Toilet paper quality suddenly drops.
This is surprisingly common. The obvious conclusion is that if someone is actually bothering to take the time to cut corners on such an insignificant expense, they probably cannot afford the larger expense of your next paycheck.Would you suggest slugging it out till we figure out our own startup idea? Should I stay if I believe in the team, but not the management?
Team is everything, at the end of the day. Sounds like you're thinking about doing your own startup with the team anyways and are just tired of management. In my experience, this is usually a big warning flag but doesn't mean the company is dead in any way. A good team can push forward!
