Strategic Staffing interview questions

They called me for the actual interview about 4 weeks after letting me know about the position. I had no notice to get ready for the interview. I was told it was the next day. I had to take time off my current job. The hiring manager for this Staffing company didn’t even show up because he was to busy bringing a former employer their person stuff they just fired. They told me two different days I would find out if I was chosen because a perspective individual blew off their interview and was given not one but two different interview dates. When I called the recruiter she became rude and said she would call me the next day in which she never did. Very unprofessional company.
