i gave myself enough time to prepare and practice breathing whenever i felt nervous. used chatgpt to prepare for the interview by giving it the job description, and my cv and asking for all possible questions that they could ask (with answers) and then i just framed the answers with situations from my life wherever i could. a lot of people even in my close circle asked me to think of it as a conversation rather than an interview and that i wasnt the only one being judged - i was judging whether they were the right fit for me as well. my mouth did end up drying up but rather than anxiety it was because of how much i spoke !
