If the interviewer brings up personal life/trying to get to k ow you stuff be totally willing to expand on your interests. The interviewer is filtering k personal skills. Simply being able to talk about a hobby is a form of bridge building between people they seem to value. Create a script. Imagine a person asks you about your free time, have conversations in your head with the fictional person.
Do the same for talking points related to your resume. Everything you put on there is a potential question they’ll ask. For example, put that you have experience with security and they are you to ask about what you’ve done or know regarding that. Pre-write an answer.
My best advice is thus: pretend to be a jacksss gatekeeper and read your application from that perspective. Write down your critique. In your head argue against that and write it down. Memorize those talking points.
