Congrats on your company's success!

However, I'm surprised that you single out a 40-hour work week as though it's something exceptional. Isn't that the standard? I would never consider joining a company that expected me to work weekends. I hope that's not as common as you imply.

Welcome to startups.

In many companies, it isn't required. But, if you don't do it , you won't get a promotion nor seen as a "team player"

Yes, it is common in my experience.
