It depends on where you are and what sort of job you’re applying for as to what constitutes good advice.

If you’re nervous, are there any things that you can do which would help you feel in control? Some people meditate, some drink a bit of herbal tea, some listen to a particular type of music. Some might get a friend to take them through an interview roleplay, though you really need a friend who actually understands interviews for that to work.

The main thing to remember is that if it doesn’t go well the world won’t stop spinning … there will be other jobs, other interviews, and practice really helps!
