Microsoft Sr Software Engineer interview questions

I applied in Microsoft Australia. The recuriter reached out to me with technical screen phone call and start the process, she mentioned there would be five rounds of technical interviews, but actually it was four. Each round included around 15 minues mixed with general technical questions and behavioural questions. 30 mins of coding, which are generally medium to hard level of leetcode questions, and afterwards by extending the coding questions to system design questions and that could last another 15 mins. With some interesting topics, the interviewers were pretty smart as well, could spend more than one hour to discussion solutions/questions with interviewees, and those discussions were pretty enjoyable! As the interviers are all around the world, interviews were conducted in early AEST time or late AEST time, I denied the ones in mid-night. In general it's a very enjoyable process. Drawback is, the interview process took VERY long, it took me more than 9 weeks, and background check for another four weeks. However, I did enjoy some time off between jobs.
