Koch interview questions

First round was based on communication and behavioral questions, 2nd was technical. I was interviewed by a person with slightly more experience than me. The interview process went for approx 30 mins covering SQL, SSIS and Power BI. Although, I wasn't asked a single question on the SSRS part, the feedback I received said: less knowledge in SSRS and SQL. I wrote them asking if there was a miscommunication, they are yet to reply to it. The interviewer seemed amateur with no knowledge of evaluating candidates' knowledge.
