Asking about the coffee could be a great way to round off the interview if it’s going well or to break some ice and make a connection.

You know how sometimes everything’s a bit straight-laced until some common ground is found? (no pun intended…)

(Also, it could be a hilarious way to tease a recruiting agent “yeah, the job was a great fit, but I just couldn’t work with instant coffee, it’s not 1980.”)
