Unity Software Development Support interview questions

I was contacted by a recruiter on Linkedin and applied online. I was then invited for a phone interview after which I was told I they would be in contact in about a week to organise an on-site interview. I heard nothing for several weeks so I contacted them for an update in which I was told there had been some delays and they would be back to me in a week or so. Three weeks later I received an automated email telling me I'd not been successful.
