It doesn't look good to be late, or to turn up without something important. As well as making preparations for the interview discussion, it is important that you prepare the practicalities as well. Work through this checklist to make sure you have everything you need:
[ ] Correct time of interview (plan to arrive 15 minutes early) and exact location
[ ] Letter inviting you to the interview with the name of your interviewer
[ ] The organisation's telephone number
[ ] A copy of your CV and/or application form
[ ] A list of the key points you would like to make, and the questions you would like to ask
[ ] ID or proof of right to work if the organisation has asked you to bring these along
[ ] Directions/map and, if using public transport, bus/train timetables and (money for) tickets
[ ] If driving, an idea of where to park and change for parking meters if necessary
[ ] Don’t forget your umbrella – it’s not good to arrive drenched!
[ ] Make sure you have factored in time to have something to eat well before the interview - and avoid anything that will repeat on you during the interview!
If most of this list is stored on your smartphone make sure you have a full battery and consider taking a hard copy of the contact number and address just in case of emergencies.
If you can't attend
It is not always possible to attend an interview on the day stipulated in your invitation. Recruiters will understand that you have academic or family commitments which sometimes can't be changed. If you are really unable to attend the interview, contact the person who has issued the invitation as soon as possible and ask politely whether it can be rescheduled.
