OP, im in the same boat as you - got a few interviews lined up.
I had an interview the other day, and I wore:
- White shirt
- Regular cuffs, not sure that wearing FC is a big deal but best to avoid any misconceptions.
- clean simple tie bar
- white pocket square tv fold
Interview went well, and i'm going in for round 2.
Dress professional and smart, don't over do the accessories, but know what you are doing.
