I got a job interview! Any tips?? - Beehaw

Hi yall after being on disability income for years and job searching for months I finally got to step two of the job search process: a job interview. I am wondering if anyone had any tips for the job interview process? I am very nervous.

Be nice to everyone, from the receptionist upwards, and if you're offered a cup of coffee/tea, offer to wash the cup yourself afterwards. Little things that show you're thoughtful.
I once had a guy loudly complain that I hadn't brought sparkling water to the session. Needless to say, he didn't make it to the second interview
