Jagex UI Designer interview questions

I wasn't interviewed after being offered an interview. I applied for the job in January, was contacted in February for an interview. This was following a previous application, where they told me the job I had applied for didn't exist (I applied for it on their website so it did exist?) and they told me they would contact ME when a role opened up - after sending 3 emails to the person who had told me this when a new position opened up and hearing nothing, I decided to apply regularly anyway. I gave them a week's worth of dates and heard nothing. I emailed again and again, nothing. I was eventually told that they'd changed the job specs, and no longer wanted to interview me.
