The interview was on HireVue. It included two LeetCode-style questions: one medium and one easy. I wouldn't say it was too difficult. You also had to record a 2-minute video explaining your thought process for the code. It was good.
They asked the Happy Number question from LeetCode. I don't remember the second one.
