The worst interview I've ever had. I received a screen call from HR, which was standard. However, once I met the interviewing manager, that's when things went downhill.

The interviewing manager was 10 minutes late, and when he finally joined the call, he did not even apologize nor address his lateness. Then he introduced himself but did not give me any chance to introduce myself nor ask him questions.

After that, he went straight to a LeetCode question that has nothing to do with their everyday work. Throughout the interview, he was very disinterested. When I finished my work and told him I had finished, it was clear he was not paying attention, as he did not respond for nearly 5 minutes. I could see through the reflection in his glasses that he was on Messenger.

After the interview, I quickly emailed the recruiter that I am not interested in continuing. This interview was one of the most unprofessional and disrespectful processes I've encountered.

Create a function that returns true if the input is a power of 2, otherwise return false.
