Whats the size and makeup of the team, how many above/equal and below. Joining as the only junior or to a whole raft of equals means promotion could be a pipe dream.
What are you working hours/environment – similar to the suit one but also will you get fired for arriving 5 mins late but always be expected to work late.
I doubt I could go back to rigid hours.
Do you encourage cycling to work? – Allows them to answer and will let you know what they think of it.
Depending on the role but important to most of mine – what is your travel policy.
If there is some sense of humour going on ask them what they like about working there.
