“A bit superior to his job,’ they always said, ‘not the kind of man who ought to be doing this.”

The quote is referring to Bakha, who is taking up a position as a sweeper. People wonder why he’d take a job that’s below him, given how he functions in society. The job of a sweeper is perceived to be for low-life members of society, the job seems frowned upon. Given that his father is a jamadar of all sweepers, a position of power, people of society view it as strange and baffling that the son would be a sweeper and not in a position of power.
