First round interview: A 15-minute phone screening with simple behavioral questions. Afterward, you’ll receive an email with an English proficiency test, including multiple-choice questions, true/false questions, grammar exercises, and a short writing task, as well as a basic Excel test. Second round interview: This round consists of three interviews. The first is with HR and is similar to the phone screening but with more in-depth questions. The second and third are with two different business managers and focus primarily on case analysis.

First of all, there was a phone interview. It was just asking about my studies and things based on CV. And then there were excel studies (which were not difficult) and lastly, in-person interview including HR and task/case studies in the office in Cologne.
