The recruiter from Texas was very kind, very friendly, and very helpful. I passed the phone interview using collabedit.com.

Then, I had an onsite interview.

The first interviewer asked me to code this problem: Write a function that takes two arguments: a binary tree and an integer n. It should return the n-th element in the binary tree in the inorder traversal. I struggled quite a bit but got it right in the end.

The second interviewer asked some network monitoring questions. He was not impressed.

Then there was a fire alarm. Everybody vacated the building.

A few days later, I was told that I was no longer a candidate.

They never asked questions about my past experiences. I guess the strange culture lives on. As long as FB is doing OK, there is no reason to change, I suppose.

Write a function that takes two arguments: a binary tree and an integer n. It should return the n-th element in the inorder traversal of the binary tree.
