Twilio Software Developer interview questions

Sent me interview invitation , but did not call me and did not respond me , so I curious why they even invited me. Probably hr people not really competent

1. Interview with recruiter; 2. Hackerrank challenge; 3. Call with senior talent manager; [decided to stop here] 4. 5 interviews 3 of them technical (design, coding, general Q&A) The call with the talent manager left me very unimpressed (she did not know where I was based, laughed at the salary expectations but refused to give any ranges because it is proprietary info (?? this will be mandatory within the EU soon)), just seemed largely disinterested. Somehow the feel (and apparently initially discussed salary range) was wrong and decided to not pursue this further.
