Thanks for this advice. They're a great team, I know they'll move on to bigger and better things; but I know it will be stressful for them in the short term.

Being honest should be easy, because I will lose nothing by doing it.

I've run interviewing workshops in the past; as part of a diversity outreach programme for a FAANG and also just for friends looking for career changes/upgrades. So I'm sure I could put something together for anyone who feels rusty.
