Got invited to do a Hackerrank challenge for the new grad position. After that was invited to on-site for their group interview day. Did 3 rounds of interviews that I thought were very easy. Weeks later was told that my technical skills weren't up to par. Based on my conversations with the other candidates following the interviews, they asked everyone the same questions and I performed at the same level or better than the others. They must have extremely high expectations or not that many open positions.
