Twilio Software Engineer New Grad interview questions

Initially a phone discussion with recruiter, and after that a coding interview on phone which was not that hard. I was called on site after that where there were 4 rounds. They noticed me for only three days before the interview that was not good. at least a week would be fine. Out of 4 one was coding, HR, database schema, architecture

The interview process is extremely slow, it takes them 2 months to give me feedback about onsite interview. Basically, they don't care about interviewee's feeling at all. Besides, it takes me one month to move on to next step after I finish the OA, another month to move on to onsite interview after I finish the phone screen interview.
