The interview was scheduled by HR and was supposed to be an HR interview. Nevertheless turned out to be a product interview. Ultimately the manager clarified the position which wa different than my expectation and we proceeded with a typical STAR question about "tell me a time... and specially focus on the discovery and data gathering part of the project". Though the example provided wasn't the best I could had found, the interviewer rather tried to press and understand what I created. On the interview round I asked the inverse question "which was the discovery process at zalando". Turned out the interviewer was interested on mentioning "I talked to clients and I actually did first hand customer interviews"
