Adare Pharma Solutions Formulation Scientist interview questions

I applied on their website and was contacted two weeks later to schedule an interview with the HR. Although I did reply immediately with my availability for that week, it took them almost two weeks to confirm the date of the phone interview with the HR representative. Phone interview went very well and was told that the scientific director will be interviewing me over the phone. An interview was scheduled. On the interview day, I was told that my interview was cancelled.
