Twilio Senior Software Engineer interview questions

Skype Call with Technical Recruiter for 30 minutes, basic hr question asked and went well got to know that another person is onsite already and may have chances if somehow his does not get through but a week later was told and they would reach out to me next time with another opportunity. Liked the interviewer, nice tone, open and friendly.

I passed the first two interview but got rejected after the third one. First interview: phone screening - recruiter; just chatting nothing technical nor behavioral Second interview: Skype - Team leader; chatting in technical and behavioral topics Third interview: phone + coredpad - Team leader; coding question and technical question about what would you do or how would you solve a problem he mentioned. My only concern about the interview is that I have a different background than web services they asked. but I mentioned that during the first two interviews and even the second interviewer (Team Leader) said that he has no problem to hire a software engineer who willing to learn something new. But my experience with the third interviewer wasn't good, he didn't read my cv before the interview. So of course his question's level was for an experienced one.
