You could argue that any interview reflects the organisation doing the interviewing.

For instance, if situations like this one happen often in the organisation, then that might be a negative symbol for the job as it indicates a lack of rigour in gathering and specifying requirements. An interview question like this could prove to be telling, and have a negative impact on hiring.

Likewise if the interview is unfocused and rambling, or the interviewer is looking for a particular answer (not just a working answer), or the interviewer just talks about themselves, etc.

These are all hypotheticals, of course: it's up to the interviewee to determine how likely these are for a particular organisation. It's useful to keep in mind when interviewing, though.
