Microsoft Senior Software Engineer interview questions

They asked me what i did in my lat job. Why we used ... and why we did X and not Y.... The to implement a Promise class, with chaining promises and Promise.All.

Recruiter contacted me in LinkedIn. Did a online coding round in Codility, after that, I was invited for the virtual interviews. Virtual interview consisted of 3 rounds (1 behavioral, 2 coding/design) Positive: I enjoyed the 3 virtual interview rounds, the interviewers are very nice and I had a really interesting conversation with all of them. Negative: The communication/interaction with the recruiters was very bad, most of the emails where automatic messages and it seems that the didn't even care. After the virtual interviews, I received a email saying that there were going to make me an offer and that the offer could take form 1-3 weeks. I was completely ghosted after that email, I even tried to get in touch with the recruiters and even cc everyone I could but didn't get any response.
