Does anyone know if its possible for an employer to find out if a candidate actually has the 'O' Levels they claim to have if the candidate took the exams over 20 years ago.
I don't know, but quite honestly, if twenty-year-old exam results are the best evidence a candidate can offer for his/her suitability for a job, they're unlikely to be appointed. I would have expected a candidate to show evidence of some self-development since then.
