Indium Software Data Analyst interview questions

Test cleared, 1st Interview went well, 2nd Interview was a shocker, I was told to prepare for SQL Window function but no question was asked on window function, Some Join questions asked which I answered and then one aptitude question was asked and interview was done! It was as if they had decided to either Select or Reject me, even before the interview. But after the Interview 2-3 Weeks Passed No communication from HR, Not even Replying to Multiple Reminder emails. They simply don't care. So don't keep any Hopes if you are giving interviews for this company.
