I applied on the web and after that I received an excercise I had to complete in 30 minutes about real examples of issues related with the production. If you are succesful, you will receive an email in 2 or 3 days after completing the excersise saying that you have reached the final stage and that you need to have 3 30 minutes interviews with Operation Managers or Area Managers. You really have to focus on the 14 leadership principles as ALL of the questions you are going to get will be based on them. Once you finish the interviews, you will know anything in less than 5 working days, an email if you have been rejected or a phone call if you have been succesful. I received my call 2 days after I finished my interviews and got an offer on the next day. If you are not succesful, don´t bother asking for feedback because they will never reply you.
