Ask HN: Am I harming my career by working around 40hours/week?

I try to work around 40 hours, sometime 45 hours when I'm stressed and I misestimated how long a ticket will take. But then I see places like Coinbase that officially state that employees need to work a lot more than 40 hours.

Review on Glassdoor: "- the exec team is very disconnected : the latest example is the CPO trying the employees that 40 h per week is not enough, when most of the comment is working 55+ hours"

This is their response:

"Chief People Officer

Thank you for your feedback. We want to ensure the promise of working at Coinbase matches the experience of being here. In the last 3 months, we’ve hired ~600 people. It is important we reiterate how we are thinking about building our company and culture at this rate of growth. We want to be transparent that there is no initiative in place to specifically reduce the intensity of the hours our jobs demand, and that we don’t intend to limit our ambitions by a traditional 40 hour work week, and come together to continue to build Coinbase."
