They've now turned to Alex for help to find the right person.Over a week, Alex will offer up nine candidates to be put through a rigorous interview process. As well as demonstrating their technical cooking skills, all candidates will have a face-to-face interview and a chance to cook a signature dish which shows off their culinary flair.
