It is common for interviewers to substitute bracketed text for the subjects words in order to paraphrase for brevity or clarity.
Example: I took Washington Street, Market Street, and Western Ave to work today. [Those streets] were terribly backed up for no apparent reason.
I have seen this convention used for a very long time…. The thing is, I don’t ever remember being taught what it means.. Did I just infer the meaning of the brackets from repeated observation or was I taught this explicitly? How about you?
