Twilio Software Engineer - II interview questions

I received an email within ~a week of applying from the recruiter to set up the call. The recruiter was aware of the position/team and interested in knowing about my background. He explained to me the process and informed me about the online coding assessment. I completed the online coding challenge and got invited for the onsite interview. Onsite-interview was very well organized. It consisted of 4 rounds including coding, system design, behavioral and technical-behavioral. After onsite, the last round was on a video call with the Director of Engineering.
