Epicor Software Associate Technical Support Engineer- B2B interview questions

I got a mail directly from Epicor Software. I was interviewed in Bangalore. Process took 1 day. The first round was online Technical round which had questions mainly from HTML, CSS and SQL from Hacker rank. Second round was GD. Topic given was "Social Media". Nothing was mentioned about the GD though in the mail. The third round was Online Versant Test. After clearing the third round, I was asked o stay for the fourth and the last round of the interview with the Manager. After a long 4 hours, I was interviewed with the manager. He asked few technical questions, asked about my current job role and explained me about my job role in Epicor. We discussed about the project that was to be assigned to me and about the salary. After the 4th and the Last interview, suddenly the HR said that I have one more round with the Hiring Manager. He started asking few technical questions and few managerial questions. Then the HR said that she will call the next day and will say the result. But the call NEVER came.
