First two rounds were online, i was shortlisted for the final HR round for which they called me in office, the HR round went smooth, everything seemed fine, but later that day i got a message that they won't be moving ahead with my application, when i asked the reason, i just got a vague reason that my energy and confidence was not good, which wasn't the case at all, i had a good discussion with HR, underconfident and low energy folks don't usually do that.
