"Guy Goma, a graduate from the Congo, appeared on the news channel in place of an IT expert after a mix-up.
But Mr Goma, who was wrongly identified in the press as a taxi driver, was really at the BBC for a job interview.
Mr Goma said his appearance was "very stressful" and wondered why the questions were not related to the data support cleanser job he applied for.
The mix-up occurred when a producer went to collect the expert from the wrong reception in BBC Television Centre in West London. "
