They were also asked to pull funny faces and some were photographed while dancing to the song.
The bizarre requests came as the job hunters attended an interview at B&Q’s Norwich store.
Some of the interview candidates said in national newspaper reports that they felt like idiots.
The company said the request was not a normal part of its selection process but that individual stores were encouraged to ensure candidates were relaxed before the formal job interviewing process began.
A spokesman said: ‘This session was run as the Norwich store was looking to recruit a large group of store based staff. The candidates were offered tea and coffee when they arrived and this was followed by an icebreaker before the formal interview process began.
‘We made it clear to all of the candidates that they did not have to take part if they did not feel comfortable and that it would not influence the recruitment process at all.’
