Twilio Technical Support Engineer interview questions

Cleared the assessment session with 5 questions. Interview lasted for around 4 hrs in 4 sessions. 2 session was regarding problem solving and general approach. 1 session was based on basic technical skills.

First I had a meeting with recruiter but he did not attend then I wrote to scheduling coordinator he was also in the cc in the mail,coordinator set another meeting with recruiter.Again recruiter didn't come to the interview after my mail he said that he forgot.I had an interview one year ago with hiring manager for this position also,definitely I can say that they are not open for diversed backgrounds and experiences,although I had a relevant experiences they made me feel really bad both last and this year.After cancelling 2 meetings we could meet with recruiter and he tried to demotivate me for the role keeped saying if you are in the last stage with another company don't wait for us I told him 2-3 times that no I don't have any other meeting with another company and want to move forward for this role then he said don't wait from us news at least 2 weeks because of christmas period and I said it is ok because christmas time….Why then they are calling me for interview then trying to push me this was a really bad interview experience.
