The Guinness Partnership Customer Service interview questions

Competency based interview with two Customer service managers. A telephone based role play with a distressed customer and a written test. Was a fairly straightforward interview, the interviewers were both very nice, professional but friendly and gave me time to think of my answer and probed for further detail where required.

COMPLETE DISGRACE. Interviewer was very rude and wanted an explanation as to why i was 4 minutes late. When i explained to him that i was not being let in by the barriers outside in the car park he just completely ignored me as if to say i had no explanation.
