Arm Graduate IT interview questions

Group assignment was good. I received good feedback but was not offered a job, despite them saying at the beginning that there would be jobs for anyone good enough no matter how many there were. Never told why I didn't receive an offer despite good performance. Feedback incredibly sparse. Test scores and one or two generic sentences. Of course, I was dropped like a hot plate after the feedback email. My calls are dropped and my email go unanswered. Especially frustrating when all I now want is the £60 it cost me to get there, which they promised to cover.
