SPS Commerce Customer Operations Analyst interview questions

The HR lady was a nightmare to work with. She contacted me about a job and I replied shortly after. So I waited for a response and I emaild her again a days after not hearing back from her. So over a week has passed and she finally contacts me apologizing that we couldn't connect sooner but gives no real reason. After all that, we were able to set up a phone interview. So a few days later, I'm ready for my interview waiting by the phone. 15 mins pass the time she was supposed to call me, the phone finally rings. But ooh, it gets better, she calls to reschedule my interview for a later date......I agree because what choice do I really have. I finally get a phone interview and she comes off as she doesn't care for the interview. Like she was doing her due diligence and just wanted to get through the interview as soon as possible. She told me she'll contact me some time the following week. It's been over 2 weeks and I haven't even recieved an e-mail or anything. I mean, at least send me a rejection letter so I know. This was by far the most unprofessional HR representative I've worked with.
