ClickBank Software Engineer interview questions

Applied online, received an email asking for a phone interview. I said I was available at any time for a phone interview. They said they'd get back to me with a date and time. Days pass and I finally get an email again apologizing because they've been busy and that they'd get back to me by the end of the week with a date and time for a phone interview. Two days later I get an email saying I'm no longer being considered for the postion.
