I had such an interview once. The recruiting agent explained to me beforehand that this is kind of a "stress-technical" interview, supposed to test my real knowledge as I would have to answer the questions without thinking, almost instinctively.

My interview happened on the phone while I was commuting on a crowded train, and was extremely successful - at the end, we both agreed that we were not looking for each other :)

This was back when leetcode was just coming in full swing (early 2010s), which since then replaced it completely. I think the (startup - coincidence?) company that was trying to hire simply didn't have the money to pay for a leetcode hosting service, a phone call costs nothing after all, only time...
