A couple of months after I sent in my application, a recruiter contacted me.

We scheduled a time to speak with someone from the Ad Platform team.

I had a one-hour interview. The beginning portion was behavioral, and the last 15 minutes were on CoderPad.

The interviewer asked basic questions he could think of off the top of his head, and I had to implement them. He then asked some data structure questions.

We developed rapport at the end by talking about his life and mine.

My scheduler replied to me afterward, but my initial recruiter was out on medical leave after the interview. I was then ghosted by the new recruiter when I reached out to inquire.

What is a binary tree?
