I want to second this, we should never ask people to agree to something below the calculator. But of course the applicant and the interviewer might disagree about the appropriate title and experience factor for a candidate.
We have to decline 200 applicants a week at GitLab. We realize that interviewing is very stressful. We send a survey afterwards to get a net promoter score. The current average is 4.2 out of 5 for people that did not sign with us. Most applicants don't fill out the survey, we're not sure how that influences results.
You are saying most people don't do the survey and I think also most would think it matters how they rate the company for their own future prospects. 4.2 is actually pretty low considering this.
If you're actually calculating an NPS, the non-respondents should be considered detractors for a more accurate rating. Happy to talk more if you're interested (have done a lot of this as a user researcher).
