Quest Diagnostics interview questions

I filled out the application, received an email to schedule an interview with one or more of the managers and a list of things I needed to bring with me. Then I went on the scheduled day, arrived about 10 minutes before scheduled time, and waited in reception for about 20-30 minutes until of the people I was to see came out and took me back to be interviewed. No one else was there, before or after me. Followup was lackluster to be frank. No response to emails or anything from the recruiter that originally scheduled me.
