How do you measure the success of a project?

"Firstly, I was contacted to book a recruiter interview, then got an automatic rejection. The recruiter reached out that it was by mistake and it went out automatically, an honest mistake but a bit stressful before an interview. The interviewer felt a bit confused about my experience, asking questions about things I've already outlined in detail in my resume, but again, it could be a formatting error on my end (even though I haven't had that issue with other interviewers with the same resume). The interview ended up being 80% asking about my previous company & how the team worked, which felt like I was repeating myself continuously. I also answered with the usual answers, but the interviewer would repeat the exact same question again. Overall, a weird interview, I ended it not knowing how much I actually talked about the role or my experience."
