I've only went through the first interview so I don't know how the others will be yet. But for the first one it was almost like a conversation rather than an interview. They just asked some basic questions like why Aldi and a few scenario questions
1st round interview is a virtual interview answering a series of prompted questions. 2nd round virtual teams interview with a DoO. 3rd round in person interview with DoO & VP.
5 rounds of interviews Multiple days and multiple People. Not bad overall. It was a solid process and they did well. The interviewers were all nice and listened well. I would recommend looking into the company first and doing some solid research.
