I applied online through Facebook's careers site. To my surprise, I was contacted on my cellphone about an hour after submitting my application by a Facebook recruiter. He asked me a little about my background and visa status, and then set up a phone screen for the next day. During this call, he mentioned he would ask more in-depth questions about computer servers. This initial phone call lasted less than 10 minutes.

The next day, I received the call for a 30-minute interview. I was asked more in-depth questions about my previous experience and about servers. At the end of the call, he informed me that he would share his notes with the engineering team, and they would decide whether to move forward with my application. By this time, I already knew it was a long shot, as my background didn't seem to be a good fit for the types of questions asked.

Two days later, I received the rejection email thanking me for my time and stating that my background didn't fit the position, which I had already anticipated. The entire process took 4 days, making it quite fast. The recruiter was consistently professional on both the phone and in email.

Past experience was reviewed.

Next, I was asked about different server types or topologies, which I didn't know.

Then, I was questioned about the general configuration of a server (CPU, northbridge, southbridge, PCH, MCH, etc.).

My experience with Linux and any scripting languages was also assessed.
