Microsoft Interview Questions: What to Expect and How to Prepare

Microsoft Interview Process

At Microsoft, the software engineering interview process begins with a resume screening, followed by one or two Online Assessments (OAs) focusing on coding and problem-solving skills. This initial screening is crucial to advancing to the next stages.

Successful candidates then proceed to a phone interview, often involving coding challenges and technical questions. Highly competitive, the process culminates in several onsite rounds that evaluate coding proficiency, algorithmic skills, and cultural fit with Microsoft's dynamic work environment.

Initial Screen

At Microsoft, the initial screening involves a thorough review of resumes, focusing on relevant experience and specific technical skills. Typically, candidates may also face automated online assessments (OAs) to gauge coding and problem-solving skills.

Following the resume and OA, a recruiter may conduct a preliminary screening call. This discussion usually touches on the candidate’s background, interests, and alignment with Microsoft’s core values and technology focus.

Phone Screen

At Microsoft, the interview process typically includes one or two phone screens. These initial calls are designed to assess your technical skills through coding exercises and algorithm questions, as well as a review of your previous projects and experiences.

The phone interviews are not just about coding; they also evaluate your problem-solving approach and your ability to communicate effectively. It's a great opportunity to demonstrate how you tackle challenges and think through solutions.

Onsite Rounds

During Microsoft's onsite interview rounds, candidates typically face four to five interviews. These sessions are a blend of coding, system design, and behavioral questions, designed to assess both technical proficiency and cultural fit.

The interviews are usually conducted back-to-back, with each lasting about 45 minutes to an hour. Candidates may also be asked to solve problems on a whiteboard, showcasing their ability to think and code under pressure.

Final Rounds, Negotiation, Offer

Post-interview at Microsoft, candidates may undergo team matching and final reviews. This phase could include meetings with executives, and the offer stage allows for negotiation on the terms of employment.

Microsoft Technical Interview Questions and Patterns

When gearing up for a Microsoft software engineering interview, it's crucial to acquaint oneself with a broad array of coding problem patterns. Basic DSA, Backtracking, and Two Pointers emerge as the most common problem types. However, Microsoft’s coding interviews seem to have a slightly higher than usual inclination towards Backtracking problems compare to other companies. It is also interesting to note smaller but still crucial segments like Graphs and Simulation, which are less frequently encountered but could be decisive in securing the job. This variety demands a well-rounded preparation strategy beyond the typical focus areas.

Microsoft Interview Coding Question Difficulty

At Microsoft, the coding interview problems generally lean towards a high but manageable challenge. Candidates frequently face questions involving Backtracking, Dynamic Programming, and Two Pointers. While rigorous, these problems are typically not as intense as those posed by Google or Apple, offering a slightly more accessible difficulty level for candidates.
