I agree, TUI will have set criteria and scorings and if you make the mark you're in, if you don't you're out. Its unfair to say someone's hard work is due to nepotism. Knowing someone at any company would certainly be helpful for any industry and company. I'm sure we would all offer advice on a business if our friend or family was applying but certainly not be able to give them a job or an unfair advantage at a massive company.
