BAE Systems Delivery Graduate interview questions

Online Application, Telephone Interview and Assessment Day.. Got to the assessment day and was told I'd hear back in a few days with the outcome. However, 2 weeks went by and I heard nothing. I chased it up and they gave me an excuse saying that they had just gotten the feedback in.. (ironic how it came the same day I chased it up) and the feedback had nothing to do with the role I applied for, I found the experience quite unprofessional if i'm honest and they took around 3 months to reimburse my travel expenses (after chasing that up about 10 times).
