When you arrive at the office where your interview is to take place, you might start to feel that your nerves are getting the better of you. However, introducing yourself to the secretary or receptionist can be a great way to calm those nerves, as it gives you a chance to talk about something that is familiar to you and that you don't have to think about. It will also help to get your voice 'in action' so that you will be able to start your interview with your normal voice rather than a nervous, high pitched squeak.
After introducing yourself politely ("Hello, I'm ... I've come for an interview with ...") you may feel that you want to continue the conversation to further settle your nerves, with questions such as "What's the agenda for the day?" or " Do you have any company brochures I can read while I'm waiting?". However, if the receptionist or secretary is busy, you should be aware that their responses may be limited. However, if they do have time to talk, avoid becoming over familiar, as your conversation may be reported back to your disadvantage.
