Sanofi Scientist interview questions

An HR staff emailed me to schedule a phone interview that was to be conducted by another Sanofi senior recruiter. I responded within an hour to confirm my availability, phone number and ask for a different time that was just 30 mins later than the time suggested. HR emailed back the day of, just 3 hours before to confirm the time and interview. Interview time came and I received no phone call. They stood me up for the phone interview! Emailed HR person back after 20 mins to check if they are running late, and I gave them my phone number again. No reply. After an hour I wrote to HR again saying I had to return to work and would like to reschedule the interview. No reply. I called and left a message the next day. Later that night I finally got a response from HR saying that there was a glitch in their application tracking system and that the manager hadn't forwarded the right application. They also said they wouldn't be considering my application at this time. Even though I got an apology in the end, I feel like their choosing to stand me up and ignore me for over 30 hours was very rude and unprofessional. They could have at least cancelled the interview last minute instead of wasting my time.
