Did 5 rounds with this company. There was only supposed to be 3 rounds but they brought me in 2 more times to do a presentation and a product demo for the team. They said it was because there was another candidate and it was a super close race. I aced the interviews and the last two challenges. Unfortunately after spending all that time and energy preparing and then knocking it out of the park, I still wasnt picked because my final round (product demo) apparently lacked enthusiasm
