I applied online. I was contacted a month later by an HR Rep. I forgot I had even applied.
When the HR rep emailed me I started looking through my emails and found the position I had applied for and looked online and found that the position was closed. I emailed her and asked her since the position I applied for was closed what position was she emailing me about, she stated it was the same position. In her original she stated that she wanted to "meet" so I emailed her back and asked her to clarify if this was going to be an onsite interview or a phone call. She clarified that it would be a phone call so I responded with a date and time that would work for me and I never heard back from her. Completely unprofessional behavior.
