They're round because, given that they have bevelled edges, that shape makes it impossible to drop the cover down the hole.

There is no right or wrong answer here. The hiring manager is trying to understand the thought process you go through to answer a question.

They are round because the shaft that you descend into, after removing the manhole cover, is round.
