I had two interviews. Both similar and I have been asked some energy related questions and some logical questions. In both interviews there were also a case study. I applied for a data analyst position first and then after the first interview they suggested me another position. I haven't received feedback from them yet after a month after the second interview where they told me that they will give me feedback in a week. The whole process took like 3–4 months which I find very long and unprofessional.
