The latest task was loosely based on construction as the two teams were charged with winning and carrying-out DIY jobs across London.
The teams were led by Stevenson and Brett “the Builder” Butler Smythe battling it out to represent construction.
But Stevenson’s side were beaten in a one-sided contest which saw her team offering their services for less than the minimum wage while bodging a series of jobs.
She was then fired from the boardroom within minutes of the result being revealed without having the chance for the traditional few minutes of bickering and pleading.
Stevenson said: “It’s my industry and I just ballsed it up”
Stevenson was followed out of the boardroom by boutique owner April Jackson and sales account manager Mergim Butaja in a bloody week for would-be business people.
