I was contacted by telephone by HR and programmed for an online interview.

I had 30 minutes for two problems:

1. An inorder traversal of a binary search tree.
2. Given two rectangles intersecting or overlapping together in any corner, how do I determine the total area for the two rectangles without the overlapped (intersection) area?

After the online test, I went for an onsite talk.

First, I had a small chat with the HR lady who questioned me about my current job, my plans, and my salary expectations.

Second, a technical interview; some of the questions were:

1. Hardest bug you ever encountered.
2. OO concepts (inheritance).
3. Nullify an integer in C++ using just while and increment operators.

Last, I had a chat with two managers about my work experience, and they presented the company culture, etc.
