"Innocuous" icebreaker questions about hobbies, the weekend, or whatever, can be surprisingly problematic.
The questions and answers often inadvertently imply things about family status, religion, physical ability/disability, socioeconomic class, age, heritage, etc. that interviews are supposed to steer clear of.
For me, this was best illustrated by one of the https://www.linkedin.com/in/lornaerickson/ funny video skits, in which the interviewer character was using "innocuous icebreaker" chat aggressively to try to extract information all over the no-no list of things you aren't supposed to ask.
(Then the skit was funny again, after the fact, when I was in an interview with some barely-out-of-school founder, who was intentionally doing one of the things from the skit...)
