"The interview process started with an introductory conversation with HR. The next round was scheduled with the hiring manager. The hiring manager canceled an hour before the interview, no explanation. I sent a note to HR to inquire about the cancellation, no response. Three weeks later, I received a response from HR to move forward with an interview with the hiring manager. The hiring process is broken at AB and should be evaluated by the head of HR. The HR representative responded to exactly zero emails / follow-up notes. Seemed very lazy and unprofessional. Lacking basic communication skills, which is not usually a skill trait that I would expect from someone who is representing the company externally. Hopefully, this is an isolated problem and not prevalent within the organization, but hard to say.
