Estacar Companies interview questions

Initially interviewed over the phone with a lady named Nichole. Interview lasted an hour and went over my experience and history. Got invited to an in-person interview a few days later. Interview lasted about an hour. Standard interview questions were asked. Didn't hear from them for several weeks afterwards. I received an email about 3 weeks later stating that the scope of the job had changed and that they no longer needed an employee with my expertise. Very unprofessional conduct and etiquette.
