As an interviewer (and former hiring manager) I find that a candidate's interest in the role and in the organisation is key. One way to demonstrate your interest is through the enthusiasm and energy you display at a job interview.
Think about how you can do this, whether your interview is in-person or online. Here's some ideas for you:
Project your voice, do you perhaps need to talk louder
Make sure your voice isn't monotone
Nod your head, maintain good eye contact
Look interested in the interviewer(s) and sound interested in what you are saying
Try not to slouch, sit up straight.
A second way that you can demonstrate that interest is to prepare your answers for questions like:⠀⠀
"Why are you interested in this role?"⠀
"Why are you interested in working for this organisation?"⠀
"What do you know about this organisation?"⠀
"What attracted you to this role?"⠀
"Why do you want this role?"⠀
"Have you any questions?"⠀
Interviewers use these types of questions to assess your interest in the role, so make sure you have your answers ready for these. Make sure you prepare your answers to questions like these, so you are prespared for them at interview.
