nope, quite common in tech companies also I work for a US tech company, my manager in my one to one weekly meeting just outright told me if I want work 9 to 5 only also can... If I want slowly get promotion also can.

So ya what Raymond say is quite accurate. My company people promotion is very two year cycle one. If u want slowly work and take it ez can also get promotion, just that it's four years instead of two
