even as a full-time manager I have never had anything like 35 hours of meetings a week. No developer has that either. IME a developer who says "I have a lot of meetings!" is at < 10 hr/ week. Something like standup (1hr) planning (1hr) refinment/definition (2hr) 1:1 (1hr) staff/all-hands (1hr) practice groups (2hr) adhoc (3hr) is what I might see on their calendar and that's a heavy - not regular - week.
