Worst Intwrview experience ever. I have more than 6 years of experience , and they assigned a guy who had less than 3 years of experience. He was a pathetic guy, all time laughing even though he was wrong. He did not even know the difference between average and worst time complexity. I can mention the name as well but do not want to spoil someone's career. I called HR and told the same and denied for further rounds.
