Answered all the question correctly. I was confident enough through out the interview that I will be selected Despite rejected by a silly reason that I won't be suitable for the role. I am shocked that in spite of giving accurate answers rejected me. And no response from them until I call the HR.

Virtual technical interview. Based on resume. Asked basics from core java, SQL, html basics, mostly real time examples. Overall good experience. It went for 30minutes. Interviewer was cool, friendly. Good coordination by HR team.
