It was a skype interview where I was unable to see the interviewer but they could see me and we talked for about 10 minutes. I had applied online several times through various job search sites (Indeed, Peersight) and emailed my resume to the location I preferred to work at as well as the headquarters for over a span of approximately a year and a half. I got my invitation for the interview about a month after the most recent application was sent. I was offered the job almost immediately after my Skype call ended (3 hours later via email).
