The interview process was smooth. Somebody who works twitter referred me. They contacted me within first week after I had applied. The recruiter was very helpful and also answered my question prompt and in very obvious way.I had three interview at Twitter. First interview was on an online platform with some very basic algorithm questions. The next two interview were also about algorithms. Algorithms used were pretty standard like : simple linked list, recursive approach and of course binary search. Even though solving problems was not pretty obvious. I was rejected after the third one.
