The Channel 4 series saw stars such as Gordon Ramsay, Mary Portas, Kirstie Allsopp and Gok Wan take over a hotel and staff it with unemployed people seeking an opportunity, while also raising money for the Prince's Trust and Springboard charities.
Across the week, employers from a number of UK firms involved in the hotel and leisure industry visited undercover to test the workers' skills with a view to potential employment.
During the live final, it was confirmed that all 14 trainees had been presented with jobs, while - as promised from the beginning - Ramsay and Portas also offered jobs to one person from each of their teams.
Ramsay selected former cruise dancer and hostess Gun from Birmingham, saying: "I'm delighted to offer Gun a role within Gordon Ramsay Holdings.
"She is inspirational and has shown an amazing level of composure and leadership in a pressurised and busy environment.
"It's been an intense week at Hotel GB but I'm so pleased to see how all the trainees have developed not just in skill but confidence and I wish them all the best for the future."
Portas picked 26-year-old Emily from Huyton, who previously had difficulty finding flexible employment after giving birth two years ago.
"Emily has been given a once-in-a-lifetime opportunity in the world of fashion to master the basics of buying, selling, styling and service before taking up a position on the floor of one of my flagship stores," the Queen of Shops star said.
