Very short notice for the interview and extremely open ended question. Hiring manager offered phone number when the interview was over and told me to me “don’t hesitate to call me if you have any questions or if you want to clarify some of your answers”. I called the managers number about 3 times the following week and never got a response. The interview felt like a grilling session yet neither of the managers had any experience in the field I was being interviewed in. Regrettable experience overall.
