Microsoft Senior Software Developer Engineer interview questions

Got referred by an engineering manager there, so my first interview was with a staff engineer. This was the worst interview experience I've ever had in my 10+ year career working at 7 companies and doing lots of interviews in between. The interview is based on these silly leetcode brainteaser kind of questions that is designed to make candidates fail if they didn't specifically study for these kinds of questions and were lucky enough to have a chance to see a question that they've seen before where they can memorize the algorithm and the answer, instead of any actual real life software engineering skills.
