CVS Health Health Concierge interview questions

They gave me an interview and afterwards called me with a job offer. I waited over two months to finish up the paperwork. During this time they will tell me that my information was under review. After 65 days of waiting to start working they told me that the position was better for another candidate. They are unethical, they just wasted my time after I received a job offer and was denied the position two months later.
