I was hired as the engineering lead earlier this year at a company. It was packed full of “senior” engineers who wrote nested loops, each screen was a monolithic program with no abstractions etc. as I let them go we hired two more (we have a consultant that hired me and has been interviewing them) who were the exact same. Senior engineer, 15 years experience, etc.

Yes all of them appear to work a couple hours of day and I’d wager they get 3-4 jobs and work a few hours a day on each
