Microsoft Senior Developer interview questions

I applied on the Microsoft site directly, and haven't heard any updates for the next 2 months, in fact, I thought I am just not being selected to move forward after no response after 2 weeks so I was a little surprised to receive the updates. The phone screening interview is scheduled within a week, and I receive the update the same day that says they will move me to the next step. There are in total 4 rounds of interviews in the virtual on-site step, which I have to schedule within 2 weeks after I pass the screening round. Three out of four is the technical round, which covers the data structure/algorithm, javascript, front-end, and web-server fundamentals and skills (I applied for the front-end role). The last round focused on behavior questions and discussed my past working experiences. The interviewers are nice and friendly, making me feel comfortable so I can focus on the questions. I received the results 2 days after the virtual-onsite round, followed by offer negotiation, background check, etc, which takes around another week. Besides the extremely long waiting time in the beginning, everything else moves fast and smoothly.

Initial interview with a manager, flurry of emails with recruiter to setup the interview loop, and then the interview loop with 4-5 different team members. Coding is mandatory and it ranges from CS specific questions, to actual real world situations. Behavioral questions etc. Most interviews I had were a great experience, with one or two being little over the top on the coding questions.
