Indeed interview questions

My first phone interview was great, the gentleman I worked with was attentive and responsive during the entire process. When I got to my second interview, the person called 15 mins late and according to my current boss, who knows said interviewer, texted her during our interview without my knowledge. I was unaware of this until my boss cornered me the next day. Highly unprofessional and unethical. When I had provided feedback about this to the gentleman who had set up this interview, I received no response and I am quite sure I never will. What a joke.
