Don’t be shy about discussing terms. You are selling a service and you are entitled to know the price you can get. If there are bonuses or commissions, make sure the structure is fully explained.
You should also ask about career progression, how long people stay with the company, what training and education is available. These are points of engagement not challenge. You are showing that this might be your first job but you are already looking to the future with the company.
And take notes. You’ll need them later.
