I applied through an employee referral. The process took 4 weeks. I interviewed at Twilio (San Francisco, CA) in Feb 2017
Interview
I had one phone call with a recruiter, then one phone call with a relevant team member to whom the role would be reporting and then an in-person interview with 6 people from the team. The recruiter handled things promptly and even followed up with a personal call after the interview, which was greatly appreciated and valued.
