Freudenberg Group Process Engineer interview questions

Recruiter reached out to schedule a 30min phone interview with the hiring manager. Recruiter ghosted after the phone interview with no response even after repeated follow up emails.

I came, met a couple managers, and tried to find out about the place, assignment, and conditions. I only got vague insights. They didn't really interview me. Must have already made up their minds from the phone screen and resume. I did not use Glassdoor to prepare. Now, the question below on this form asks how useful Glassdoor was in preparing and gives two choices:: Very Helpful, and Helpful. No other choices. Is that leading the witness, or what? The recruiter (staffing agency - it was a contract job) also called my references.
