3 interviews: 1. HR Interview: Very welcoming experience with charming HR representatives. It might involve a couple of behavioural questions and information about previous working experience. Also there was a little 10 mins challenge involving python and SQL programming. 2. Manager-led interview: A couple of brain-teaser in order to test your thinking process. 3. Final challenge: By far the most difficult, it involved getting familiar with the EMS platform as well as coding Python in order to get business insight from a bunch of tables. The most challenging thing in my opinion was the lack of business knowledge regarding the challenge topic.
