Two back-to-back technical phone interviews.

There should have been 15 minutes between these two interviews. However, the first interviewer was a little late, resulting in the second phone call starting before the first one finished.

The interviewers were nice, and the questions were typed into a Google Doc. Examples were provided by the interviewers. The questions were easy, and the interviewers reminded me if I was going in the wrong direction.

Unfortunately, my application was too late to find a team during team matching.

1. Determine the balanced binary tree.
2. Pattern match.
3. Longest consecutive ones.
