I assume most everyone wear a suit to these events?

You can't go wrong with that, just make sure it's not yellow.

You can't go wrong with a yellow tie.

Yes you can, don’t be one of those kiss ass douches that wears a yellow tie.

You're right, wear a red and blue tie.

Amen....
Grey or blue suit never hurt anybody. White shirt..clean and acceptable tie.
Not one single person in the history of job interviews has looked “bad” in the company’s eyes for looking good.
Look your best.
It CANNOT hurt you.
Looking like a douche definitely can.
Use your judgment

Good luck!!

While we’re talking about it, I’ve heard it said that black suits are frowned upon at job fairs. Anyone have an opinion on that? Feel like that’s overthinking it.

I've never heard such a thing. You can't go wrong with black or a dark blue.

I would avoid wearing this suit to the interview. . .
