This. I have the same problem (ie 4 roles bundled as one role) and I am so tired. After speaking to many people that are far more successful than me in their careers, I was told: 1. You cannot be successful at 4 things at the same time. I do not work like this because it is impossible. You must pick what you are focusing on. 2. Agree with your management where they expect you to be spending your time. Agree on the plan for everything else which is not in the prior category.

While I agree there is a lot of ageism, there is something worse than ageism - obvious fatigue and lack of enthusiasm during interviews. You can read burnout on a person in the first few seconds - you may need to get a break so that you can have the proper mindset for interviews.
