Diameter Health interview questions

Interview Process was decent, took 2 months and 4 rounds from interview with team, COO, CTO, VP They gave me a verbal offer but then retracted it. Disappointing experience and waste of time. This is what they send me " the team has decided to go in a different direction with the role itself given a few things that have transpired this week. I wanted to apologize for the back and forth, however, we will be retracting the verbal offer given until we are clearer on our expectations"
