How it’s done

 Way back in the last century I was sitting on the bathroom floor, a toilet bowl across my lap, scraping the nasty, failed wax ring from the bottom. The wife came in with the cordless telephone (landline) in her hand. She said it was the HR manager from redacted company. 

I took the phone and absolutely nailed that job interview sitting right there on the bathroom floor cradling a toilet. After I hung up I finished fixing the lavatory.

I got the job. 

That, my friends, is compartmentalizing and I’m still very good at it.
