I feel like I'm missing something. Why would you ever respond to that listing? No meaningful description of the company, no outstanding benefits, just the promise of being overworked?
Good question. Of course in retrospect getting that job would make you one of the all time highest earners in the software industry.
I think it is also quite clever, the only people who would ever respond to this are exactly the people you would want. The core promise here is being able to work on something which might change the world.
