I applied through an employee referral. The process took 2 weeks. I interviewed at Twilio (San Francisco, CA) in Aug 2015
Interview
Consisted of an off-site meeting with my hiring manager, a technical phone screen, and a series of onsite technical interviews. Pretty standard format. All interviewers had been trained extremely well in how to conduct an interview, and all of the questions scaled well to a variety of experience levels. Overall, my interview experience at Twilio was better than any other experience I've had. Much better than Google or Facebook.
Three-stage process: recruiter screening, a test task and on-site interview. Both test task and the on-site were simple and straightforward, with focus on practical skills. On-site included the prospective team lead, VP and a team lead from another team in the same location.

I applied online. I interviewed at Twilio in Jan 2025
Interview
Interviewed for the L2 role on the Channels team. I did the online assessment (~3 hours), passed it, then was notified saying they filled the role and were no longer considering me. No referral to another role either. Long story short, don't let this awful company waste your time.
2 algo problems (listed below), 1 easy SQL problem, 1 easy API data retrieval problem, and 2 trivial multiple choice problems.
