Implied, but by no means clear and so makes discussion a bit pointless.
Did he lie about his A levels to get onto the Business Management course and then get a job based on that degree?
Or did he get the degree and then lie about A levels, because the job required both A level qualifications and the degree?
Or did he actually not lie at all? As he's perfectly entitled to not put his A levels on his CV, even if the job states required grades. If they choose to employ him based on the info in his CV and his performance in the interview, then he's done nothing wrong - unless they specifically ask about grades and he chooses to lie directly.
As I said, OP requires more detail.
