I applied online, using the friendly Facebook career website.

I received an email followed by an informal phone interview. Afterwards, I got the chance for a tech interview.

The first questions were a little general, the "tell me about yourself" kind of thing, previous experience, and the challenges faced.

There were two coding problems:

• One based on recursion, factorial kind of thing.
• And afterwards, a question on merging two sorted arrays in linear time.

My approach solved the problem in quadratic time, and I was asked to improve it to the best I can.

At first, I couldn't really see how, but the interviewer was really nice. He gave me hints to start with. I stumbled at first because I could not immediately grasp the whole idea. I kept on saying things without changing the code until I said the right thing, and he agreed with me afterwards.

I am waiting to hear the outcome of the interview, which I have hope I passed. I will get the chance to work with such wonderful and humble people. I really liked the guy; he was so down to earth. I feel like crying right now...
