Indium Software Automation Test Engineer interview questions

They conducted interview through zoom. I cleared the interview of two rounds after that they told me to we will contact for further rounds. Till now i didn't receive any updates from them and also personally i sent mail to HR they are non responsive. Then why they are conducting such type of interviews.

I have been interviewed at indium on 3rd feb,2018.First round of interview is aptitude in which there is no multiple choice answers.we have to solve and write the answer.Programming is also there.Next round is technical which is completely from java(your known language).
