Morningstar Business Intelligence Analyst interview questions

First they gave an assessment test to complete. It was a project on power BI. I completed that and in first technical round of interview he asked to perform few steps on power BI, just to check if I have the knowledge of Power BI. And asked what is RLS. I cleared the first technical round. HR called to office for 2nd round of interview. It went really great. They asked for my documents. And after 2 weeks they ghosted. I followed up multiple times finally the HR said I didn’t cleared the round. I felt weird. They just waste your time and energy. Had worst experience.
