My Microsoft Frontend Interview Experience

Overview

Microsoft is one of the world's leading technology companies, hiring frontend engineers across multiple global offices, including Bengaluru. Frontend roles at Microsoft typically involve building large-scale, performance-driven user interfaces for products such as Azure, Office, Teams, and Edge. Given the scale and complexity of these products, Microsoft's frontend interview process is designed to evaluate a candidate's depth in JavaScript fundamentals, framework expertise, system design thinking, and project ownership.

This article presents a recent frontend interview experience at Microsoft for a Bengaluru-based position, outlining the structure of each stage and offering useful takeaways for prospective candidates.

Interview Process

The interview process was initiated by a Microsoft recruiter who reached out via LinkedIn. Following an initial exchange of professional details, a preliminary phone call was scheduled within a few days. During this call, the recruiter asked basic questions about the candidate's background and provided an overview of the overall interview stages.

The complete process comprised five stages:

• Hiring Manager (HM) Round – An exploratory discussion focused on project experience and design rationale.
• Technical Round 1 – A coding-focused round covering frontend fundamentals and problem-solving.
• Technical Round 2 – A second technical round typically focusing on advanced JavaScript concepts and framework-specific knowledge.
• System Design Round – A round evaluating the candidate's ability to design scalable frontend systems and components.
• HR Discussion – A final conversation covering compensation, team fit, and employment terms.

The interview was conducted for a frontend engineering role based in Bengaluru, and the recruiter's initial communication set clear expectations around the structure of each round.

Technical Rounds

Hiring Manager Round

Contrary to the candidate's expectations of a system design round — based on the recruiter's initial description — this round turned out to be an exploratory, project-focused discussion rather than a formal technical evaluation.

The conversation began with a brief introduction, after which the hiring manager asked detailed questions about the candidate's current and previous projects. A significant portion of the discussion revolved around the most challenging project the candidate had worked on. The interviewer probed deeply into the design decisions made during that project, asking the candidate to justify the rationale behind each choice.
