Initial contact with their HR Manager (Suzanne) was on Linkedin. They contacted me because I was currently working in a position they needed to fill in their company. We exchanged contact information. And I agreed to a phone interview. The HR Manager scheduled the phone interview with me on a specific day and time. On the day and time of the interview, the HR Manager was a no-show. I waited for 30 minutes after the scheduled time before I let it go and assumed they were not going to show. Later that day I sent an email to the HR Manager about the missed phone interview but I never received a response. VERY UNPROFESSIONAL!
