At the end of my HR interview, I said Thank you, sir, Good day! and he replied, “when you will join the company, at that time don’t call me sir, call me by my name!” This was a very big hint for selection. But still, you can not assume anything until the results are out. So I was desperately waiting for results. After the HR interview, I searched for the person who took my HR round on LinkedIn and came to know that he is vice president. Results were out after 2 hours, and only I was selected!!! I was very happy, and then I also felt bad for the other candidate who was rejected after the HR round
Tips:
- Keep in mind Time matters so much in all the interviews and do not lie for any reason.
- If not selected then don’t get upset, analyze your mistakes and look forward to the next opportunities!!
