Be well rested, get a full night’s sleep the day before

Arrive early, in case of traffic or getting lost, but if there is a problem communicate it

Never trash talk anyone, former employer or coworker, it’s a red flag

Be ready to talk in depth about anything on your resume

Do some research about the company, your interviewer. Any special projects, books, publications. You asking detailed questions will impress them

If your not desperate for a job, don’t put on a personality, act like your normal self. You want to make sure it’s a good cultural fit too

Look at the cars in the parking lot, that will tell you a lot about the company pay and culture
