This was with the Ads team, and we were a group of people from Insight Data Science who were invited for onsite interviews. One person was told to "come back when he's learn to code," and another was told to finish his problem by himself and leave after 30 mins. The one person they did extend an offer to, they asked him to solve 2-sum. It became extremely clear that the Ads team had decided whom they were going to hire before all of us went onsite, and the people they were interested in were given LeetCode easys. Why waste all of our time like this and mistreat people you weren't interested in hiring? This is a great way to destroy your talent pipeline. You may not be interested in hiring some of us today, but we may be great hires in the future, but after this experience, I will never, ever consider working for you.
