I just applied last week and have an interview today. I used to work there aswell and both times i applied through the website and haven't known anyone before hand. When answering the questions I think you should think about the fact that this business is different to others, you're a partner its more of a democracy. try to do most things on your own or with help from other colleagues but only rely on your manager if you really need it. really read the questions and take in every bit, is it a busy day, what is your manager doing, are there other colleagues around that could help. could you do the job on your own the right way without affecting the quality of your work.
