The process took around an hour. The interview was fairly technical, with questions regarding SQL and Tableau primarily. Knowledge in R and Python was helpful. Be ready to talk about prior experience.

I would say that the hiring process is too long and time consuming. I spent more than 1 month in the process, interviewing with HR, the hiring manager, working on study case (not easy), presenting it, to receive a automatic email of rejection.. Aldi could at least send an specific feedback to you so you can do better next time, because we spend time and energy of our lives taking part of that many steps and they simply send you a generic message, I was VERY disappointed. The phases were: Interview with HR Interview with Hiring Manager Study Case Interview about the study case with the Hiring Manager Interview with the Hiring Manager Boss
