I sent my resume to a referral source, who then forwarded it to the HR Generalist. Within a few days, the HR Generalist called me asking basic questions about my education and experience. She then passed my resume to the hiring manager, who also called me to confirm my education and experience. This led to a 1:1 interview with 3 employees (including the hiring manager). All 3 were very courteous and professional. I found out the following week that I didn't get the job, but that they would keep my resume on file.
