Google Manager (L6) Interview Guide
A comprehensive guide to the Google manager (L6) interview process.
The Google engineering manager interview process starts with a recruiter screen, followed by one technical phone screen covering coding and algorithms, then wraps up with an onsite loop featuring multiple interviews in coding, system design, and behavioral areas. You're looking at approximately six total interviews that typically take 4 to 12 weeks from start to finish, though team matching after passing the hiring committee can add a few more weeks to the timeline. Google's hiring committee structure makes the process thorough but sometimes longer than other companies that rely on a single hiring manager decision.
System design and behavioral rounds carry the heaviest weight for manager level candidates. Coding is still important and you must clear the bar, but Google typically places greater emphasis on an EM candidate's system design capabilities and leadership aptitude during the interview process. What really separates manager candidates from senior IC roles is your ability to articulate leadership experiences and show how you've navigated team dynamics, conflict resolution, and project management under pressure. The behavioral interviews dig deep into specific situations where you've coached struggling engineers, delivered difficult feedback, or guided teams through technical crises. Your system design performance needs to show both technical depth and operational thinking since you'll be making architecture decisions that affect entire teams.
The interview consists of approximately 6 total interviews:
- Recruiter / Hiring Manager Screen
- Technical Phone Screen (Coding)
- Onsite Loop (typically 5 interviews):
- Coding
- System Design (often 2 rounds)
- Leadership/Behavioral (often 2 rounds)
Interview Rounds
Google's engineering manager interviews follow a structured path that balances technical depth with leadership assessment. The process moves from initial screening through focused technical evaluations to a comprehensive onsite evaluation. Each round builds on the previous one, with interviewers looking for both your technical foundation and your ability to guide teams through complex challenges.
Recruiter Screen
Your Google journey starts with a 30 minute conversation that's more about mutual fit than technical prowess. The recruiter wants to understand your background, motivations for joining Google, and whether the specific role aligns with your career goals. You'll walk through your resume highlights while they explain the position and team dynamics.
This conversation happens over Google Meet and stays focused on the big picture. They're checking that your expectations match reality and that you understand what you're signing up for. The recruiter will outline the interview process, discuss timeline expectations, and answer your questions about the role or company culture.
Sometimes a hiring manager runs this screen instead of a recruiter. When that happens, expect a few light technical questions about your past projects or some gentle probing into your leadership philosophy. The conversation might dig slightly deeper into specific experiences from your resume, but it won't turn into a full technical assessment.
Technical Phone Screen
The technical phone screen brings you face to face with Google's coding standards through a 45 to 60 minute session using a collaborative coding platform (such as a shared Google Doc or online coding editor). You'll tackle one or two algorithmic problems while thinking out loud and explaining your approach. The interviewer watches you work in real time, observing how you break down problems, implement solutions, and handle edge cases.
Expect classic data structures and algorithms challenges similar to what individual contributors face. Problems might involve implementing an iterator over time-indexed data, building an LRU cache, or solving a graph traversal challenge. You'll write actual code in your preferred programming language while discussing your thought process throughout.
The format feels conversational despite the technical focus. Your interviewer will ask clarifying questions, probe your assumptions, and sometimes suggest optimizations once you have a working solution. They want to see how you think through problems systematically and whether you can write clean, testable code under time pressure.
You're evaluated on four main aspects:
- Problem solving approach: How you break down complex problems and identify the right data structures
- Code quality: Clean, readable implementations with proper variable names and logical structure
- Edge case handling: Thinking through boundary conditions and error scenarios systematically
- Communication: Explaining your reasoning clearly and responding well to interviewer questions
For engineering managers, the coding questions tend to skew more basic than those given to senior individual contributors. You need to demonstrate that you can still think algorithmically and write correct code, but the bar is typically set at medium level LeetCode problems rather than the most challenging algorithmic puzzles. This ensures you maintain technical credibility with your teams while focusing evaluation on the areas that matter most for management roles.
Onsite
The onsite loop represents Google's comprehensive evaluation of your readiness for an engineering management role. You'll typically work through five distinct interviews that test different aspects of your capabilities: one coding interview, two system design interviews, and two leadership/behavioral interviews. Each session has a specific focus, but interviewers coordinate to get a complete picture of your technical depth, architectural thinking, and leadership potential. These interviews are usually scheduled on the same day, though they can sometimes be split across two days.
Coding
Your onsite coding session ups the ante from the phone screen with a higher bar for optimal solutions and cleaner implementations. You'll work on a whiteboard or Google provided Chromebook, solving one challenging algorithmic problem or two medium difficulty ones within the hour.
The physical environment changes the dynamic compared to virtual coding. Writing on a whiteboard requires more planning upfront since you can't easily refactor large sections of code. If you're using the Chromebook, you'll work in a simple IDE without the debugging tools you're used to.
Problems tend toward the medium to hard range on LeetCode difficulty, often with multiple optimal approaches or follow up constraints that test your adaptability. The interviewer might ask for optimizations once you have a working solution, or present additional requirements that force you to rethink your approach.
Strong performance here demonstrates that you maintain sharp technical skills despite moving into management. The interviewer evaluates your algorithmic thinking, ability to write production ready code, and how quickly you iterate when requirements change.
System Design
The onsite system design interview represents the deepest technical evaluation of your architectural thinking. You'll spend 60 minutes at a whiteboard designing a complex, real world system that demonstrates both breadth of knowledge and the ability to dive deep into specific components.
Expect scenarios that mirror Google scale challenges: designing a global content delivery network, building a real time analytics platform, or architecting a distributed storage system. The interviewer wants to see you drive the entire design process, from requirements gathering through detailed component specifications.
This session goes beyond high level architecture into operational concerns that matter for engineering managers. You'll discuss how teams would build and maintain different components, what monitoring and alerting look like, and how the system evolves as requirements change. The conversation often touches on team organization and how different services get owned and operated.
The evaluation focuses on your ability to make informed trade offs between consistency, availability, and performance. You'll need to demonstrate understanding of how different architectural choices affect both system behavior and team velocity. Strong candidates show they can think like both a technical architect and an engineering leader.
"There are so many options for companies/interviewers to choose from that I was initially taken aback and a bit bummed I hadn't been asked one of the problems outlined on HI. Even more of a bummer, I'd seen the question on the Real Interview Questions page and hadn't made time to think through it!"

Behavioral
The behavioral interview digs into your leadership experiences through specific scenarios that reveal your management philosophy and problem solving approach. This 30 minute conversation focuses on real situations where you've guided teams through challenges, handled conflicts, or coached individual engineers.
Interviewers ask open ended questions that require concrete examples from your experience. You might walk through a time when you had to deliver difficult feedback to a senior engineer, resolve conflicts between team members with different technical opinions, or guide your team through a major production incident. They want to hear how you think about people problems and what your instincts are when teams face pressure.
One common pattern involves a deep dive into a significant project from your resume. You'll explain not just the technical challenges but how you organized the team, made decisions with incomplete information, and balanced competing priorities. The interviewer pays attention to how you talk about other people and whether you take appropriate credit while acknowledging team contributions.
Google evaluates three key areas through this interview:
- Collaboration skills: How you work with other teams, handle disagreements, and build consensus
- Leadership approach: Your philosophy for developing people, making decisions, and driving results
- Cultural alignment: Whether your values and working style fit Google's collaborative, data driven culture
The conversation feels more like a discussion with a peer than a formal interview. Strong candidates demonstrate self awareness about their leadership style while showing they can adapt their approach based on team needs and situational context.
After the Interviews
Once you complete the interview rounds, your candidacy moves through several additional steps before you receive an offer.
Hiring Committee Review
Every Google engineering manager hire must go through a hiring committee review. This is a mandatory checkpoint where a group of experienced Googlers who weren't involved in your interviews reviews all the feedback from your interviewers, along with your resume and other materials. The hiring committee makes the decision on whether Google should hire you, ensuring consistency and maintaining the hiring bar across the company.
This process typically takes one to two weeks after your onsite interviews. The hiring committee either approves you for hire, requests additional interviews if feedback is mixed, or decides not to move forward.
Team Matching
After you've been approved by the hiring committee, you'll enter the team matching phase. This happens before you receive a formal offer letter. During team matching, you'll have conversations with potential hiring managers to find a mutual fit between your background, interests, and the team's needs.
Sometimes you interview for a specific team's opening from the start, making team matching straightforward. Other times, you may meet with multiple teams over a few weeks until you find the right match. Once a team agrees to bring you on and final executive approvals are completed, Google extends the formal offer.
The entire process from hiring committee approval through team matching and final offer typically adds 2 to 4 weeks to your timeline, though it can sometimes take longer if multiple teams are involved or if scheduling is challenging.
