After an interview, it’s always a good idea to send a thank you letter or email. It’s a great way to express your gratitude towards an employer for allowing you the time to discuss your experiences. Don’t forget to send it out immediately after your interview. You’ll stay fresh in the mind of the employer and may even score bonus points for excellent follow-up skills.
Spend some time thinking about how well you did or how you can improve your job interview technique if you find yourself unsuccessful.
If you get the position, congratulations! And don't forget to let us know, it is always good to hear from you.
If you were not successful, call and ask the school why not. Anything they tell you will be of great help in preparing for future interviews. Ask them to be frank and evaluate their feedback carefully. Perhaps discuss it with a mentor and ask for their advice for future interviews.
