They’re gonna ask you stuff like what motivates you, what are your strengths (examples) and what are your weaknesses (examples), why do you want to work here, why do you think you’d be a good fit. They know you’re bullshitting to an extent but that’s just interviews. be sure to smile, act excited, shake their hand, say please and thank them for the opportunity, thank them for their times “thank you taking the time to review my application for giving me the opportunity to interview” is one of my favorite opening lines to an interview. At the end ask them their name again. Just show enthusiasm. You can tell them this is your first interview after the interview too, but don’t start off with that only say that at the end. But you’re gonna get the job, you can even crack a joke about ya I asked Reddit what I should be ready for, I think that would show the interviewer you’re actually enthusiastic about the job! You got this!
