I applied through an employee referral. The process took 4 weeks. I interviewed at Vertex in Mar 2014
Interview
I emailed the manager directly and forwarded my resume. I was told that I would be receiving a phone call within a few weeks to interview with a group of 3 or 4. Soon after (within 2 weeks), we arranged a time for the phone call. I spoke on the phone with a group of 4 for about 25 minutes, and then they told me they would get back to me soon.
