One phone interview, followed by onsite at Twitter HQ. The onsite had 4 technical and one behavioral interview. 4 the 4 technical interview, I would say the interviewers should change their approach a bit. They keep telling you all the time that your solution is great, your answer is great. It gives the interviewee a feel that he/she is doing perfect and no need to try it better. After each of my coding solutions, all the interviewers said the solution is great and none of them asked for any change or improvement. However, right after the interview I got the rejection letter and they said I need more industry experiment and need to improve my coding skills. They dont give you the opportunity to show how far you can improve. They never asks you "can you make the code any better?", which I believe is an essential part of any technical interview. They would keep saying it looks great and then would reject you.

An Online Assessment, 2 Virtual Onsite rounds loops, and 1 behavioral round. OA is quite easy-medium. LC Medium and Easy. Then we move to OA with technical questions, a technical coding challenge, and some behavioral questions. Onsite consists of technical challenges in each round. Behavioral questions are quite common and some preparations about the company working.
