I submitted my resume on my college's career development website in January.

About a month after I sent my resume, I received an email from Facebook stating they wanted to interview me.

They scheduled one 45-minute interview for me, during which I had to solve two different programming problems. Upon passing the first interview round, they scheduled a very similar 45-minute interview within the same week.

The entire interview process took only two weeks, and they called me about the offer within two business days. This was definitely the most efficient hiring process I've ever experienced.
