I work a very standard work week 9-5. I'm not expected to do overtime. Remote work depends on your team - some teams you'll get 3 days a week, other teams you'll be lucky to work from home at all.
9-5, 5 days a week. some teams/ managers are more flexible than others.
38 hours a week and the employer is typically very flexible in terms of remote work and other working arrangements.
My employer has made a very comfortable environment allowing flexible working arrangements. Time in lieu is always an option if extra hours have been worked.
