In case I am invited to a job interview, and in the invitation letter, recruitment tells me the names of the interview panel members. Suppose that I already know some or all of the members, through prior work engagements (including informal social events). Do I behave any differently for it, either in preparation or during the interview?
It seems a bit odd to enter such a formal situation with a greeting “Hi, Jane! Hi, Bob!". But it also seems weird to pretend that we're strangers or to be overly formal with someone I've been on first name basis with for months or years.
