I uploaded my resume to Meta's website.

After a few days, I received an email with instructions for the interview.

The interviewer was really nice.

This is my first interview.

I still haven't received an answer.

I hope I passed successfully.

It took me a little while to answer the questions, but it might be okay...

I need to return the sums of all paths from the root of a binary tree.

For example: 7 /
3 2 /
5 6

I need to return the sum of these paths: 7 -> 3 -> 5, 7 -> 3 -> 6, and 7 -> 2.

I received a sorted array of numbers and a target number. I need to return the number of times the target number appears in the array.
