A recruiter reached out, and I completed a quick questionnaire, which was forwarded to the engineering manager for review. Once I received the green light, I was scheduled for a first-round technical phone screen. They rescheduled the interview twice.

The first time, I got a notification 15 minutes prior to the scheduled time, stating they had moved the interview to a week later. The second reschedule occurred three days before the new date.

When I finally had the technical phone screen, the interviewer seemed very uninterested and would not answer my clarifying questions, offering only simple responses like, "I don't know, what do you think?"

It is a LeetCode medium question.
