Have unique questions to ask at the end. Don't ask the canned "Where do you see your company in 5 years" or "What does a normal day in this role look like" or "when do you expect to fill this role" or anything like that. They get those from every other person. Plus you should already know what the role looks like and where hte company is heading if you did any research.
Show personality and be yourself. Sure, you want to answer "yes" to every question but if you honestly don't know, say you don't know at this time and then try to redirect it to something similar you do know.
Example in IT "How experienced are you with Aruba wireless?". Me "I haven't used Aruba in a production environment....but I have configured and managed Cisco, Meraki, Ubiquity, and Juniper in many situations. I also migrated from Cisco WAPs and an onsite WLAN controller to cloud connected mesh style APs. I understand the concepts very well and I'm confident my understanding of concepts and other devices would transfer very well to Aruba, it would just be picking up slightly different syntax or different menus on the web portal"
Be honest-ish. Don't lie about what you do and don't know b/c they will find it out and then they won't believe anything you have said. And as I said, show your personality. When I've hired I look 50% personality and culture fit and 50% skillset. I can teach you skills, I can't change your fit with our company or department or change your dull personality. Show curiosity and passion and willingness to admit you don't know it all but you are extremely excited and capable of learning.
I also smile and make some jokes and be lighthearted where appropriate. I'm interviewing for a job and interviewing them as well. I'm not on trial for my life. Keep perspective if possible. I actually try to have fun and connect with the interviewers moreso than trying to get every answer perfect. You either win and get the job or you learn and get better.
