Aldi's recruitment process for the management trainees are handled through Hudsons.
I had an initial screening interview over the phone with a Hudson junior recruiter - very easy questions, just basic interview stuff. Only took about 10 minutes.
I was then invited for a 1 hour interview with a more senior Hudsons recruiter - the questions here are focused on your leadership qualities: how would you train people, solve problems, deal with angry customers, etc.
I was then successful and went onto the assessment centre round. This is essentially the final round and we had a group activity plus interview with a senior ALDI manager. It went the whole day. In the group activity we were given a hypothetical plane crash scenario and had to prioritise a list of items we would take with us.
I bombed out I guess because I didn't get the position.
