Get advice from a hiring pro
If you have a friend or family member who is responsible for hiring new employees, ask them to look over your resume. They’ll be able to tell you what questions they would ask you during an interview and highlight any concerning spots or missing information. Even if they aren’t in your field, they’ll be able to offer advice from the perspective of a hiring manager and help you see yourself from the position of your potential employer. Ask if they’d be willing to do a practice interview to help you prepare answers to any potentially tricky questions. Send them the thank you note that you’d typically send after an interview and they can critique that too!
