Before the start of a job interview, you will probably be offered coffee or tea. Even if you strive for a sip of hot beverage, remember: you are on a job interview, not in a café. Somebody would have to run to the kitchen for your order, and waiting for it would create an awkward silence.Instead, ask for a glass of water. Not only it will refresh you, but you won’t be bothering people which always makes a good impression.
