Asked to build a weather app that displayed data from a third party api. The app included a setting up a text field, a collection view and making a network call. This was supposedly a pair programming session. Instead of being collaborative, I sat with a developer who consistently mentioned how much time I had left (over four times during the hour), questioned why I was looking at documentation (although I was allowed to), blurted out clear mistakes (like a missed paranethis) before I had the opportunity to fix them and overall made the experience a nerve wracking one.
