ALDI Intern interview questions

It started with an online application and online assessments, both were very long, but not difficult.I was then invited to an interview, where I record my answers on my laptop. They only give you 10 seconds to answer a question, I was told the interviews will be on the Aldi business model, however, they were all about me. They called me afterwards telling me Aldi has a grooming policy and that I should have worn a tie and groomed my beard. As I am a Sikh I found this offensive and asked the man if he saw my turban in the video, otherwise why else would he say that. I was then contacted by head office and was sent multiple emails and phone calls apologising for what the recruitment team had told and why I did not get accepted. The really did not want me to file a discrimination complaint. As this all happening this past month I have not considered If I should or no. Aldi is a German company If you want to apply make sure you are well dressed and white, otherwise you do not stand a chance :)
