Very unprofessional company - Administrative Assistant ABC Nanny Source Employee Review

Before starting my position as an administrative assistant I was very excited and hopeful. The first day at the job I noticed the environment was very cold and unwelcoming. It's very awkward to not even know the other employees you work with especially in a small office of about 5 people. I understand being professional and active through out the day but some sort of interaction makes a job even more enjoyable. Not even two weeks into the position I received a voicemail/missed phone call from the "director of hr" but the long message was unclear so she had to call me back. The phone call started off that she needed to be honest I wasn't the right for her. I was very shocked and taken back because since being there not once verbally or written was I told about my performance. It is also very disrespectful and unprofessional to fire someone on a voicemail/phone call. I was always respectful and did what was ask of me with the little training that was given. If I would have known about their unprofessionalism I would have never accepted the position and continued to work at my previous employer that I was with for two years. Luckly enough I am receiving feedback from other employers so that I can start after the holiday season. When interviewing with the director of hr and owner they gave off a different impression and persona of the company. You would think after all the turnover the owner/management team would realize it's because of the cold work environment and unprofessionalism.
