Hi folks, I have an upcoming Microsoft interview and wanted some guidance from people who’ve been through a similar loop.

Interview structure: 1.

Problem Solving + UI Specialization -1 hour * Problem solving will be on a

HackerRank (they have shared hackerrank link) 2.

System Design

Questions I had:

Problem Solving + UI Specialization * For the problem-solving part, what’s the usual difficulty level? Mostly standard DS/Algo (arrays, strings, hash maps, etc.), or anything trick-heavy? * For

UI specialization, what’s generally expected? * Machine-coding (build a small UI/component), or * More discussion-oriented (component design, state management, performance, accessibility)?

System Design * I usually follow the

RADIO framework for system/frontend design and am quite comfortable explaining my approach that way. * One of the interviewers is a well-known YouTuber and an EM. Would you recommend sticking to my own structured approach (RADIO), or trying to align with the interviewer’s style/content? Also, is there anything important I should clarify with the recruiter beforehand regarding expectations or depth for these rounds? Would really appreciate insights from anyone who has interviewed at Microsoft recently. Thanks!
