As a first step, I received an email for a screening interview and picked a date. However, a few days later, I got another email stating that they would proceed to the second round with me, including a case study. Since the first round hadn't even taken place yet, I thought there might be a mistake. Later, during the interview, I learned that this interview was related to that case study, but it wasn't mentioned in the initial email. Apart from that, the person conducting the interview was really nice and understanding. The case study itself was also of high quality. I would consider applying again in the future.
