LoginRadius interview questions

Very bad experience. I got selected in the first round of interview and got selected to the second round. The second round also went pretty well. Later when I followed up with the HR she has sent out an email saying I have not qualified . I moved on but after 2 days I got call from the same HR saying it was a mistake you are still being considered but not disqualified. Later when I asked about next round of interview ,after one week again she called and said that I didn't qualify for the next round. I really don't understand are you people trying to play with our career and emotions or what? Or is this some kind of game to you.?
