1. What is an Engineering Manager?

At Datadog, the Engineering Manager role is a critical pivot point between high-level product strategy and deep technical execution. You are not just a people manager; you are a technical leader responsible for teams building the monitoring and security platform that powers thousands of enterprises globally. This position requires a balance of empathy and engineering rigour, ensuring that your team delivers scalable, reliable software while maintaining a healthy, collaborative culture.

The impact of this role is visible and immediate. You will lead teams working on complex distributed systems, high-throughput data ingestion, or intuitive frontend visualizations. Whether you are managing a team within Infrastructure, APM, or Logs, your decisions directly affect the reliability of the internet's most critical applications. Datadog engineers "dogfood" their own product daily, meaning you will be building the very tools you use to manage your team's operational health.

You should expect a role that demands high autonomy. Datadog values leaders who can navigate ambiguity, drive technical roadmaps, and foster an environment of psychological safety. You will be responsible for hiring top talent, mentoring engineers to the next level, and collaborating cross-functionally with Product Managers and Designers to ensure the team is solving the right problems for customers.

2. Getting Ready for Your Interviews

Preparation for the Engineering Manager interview requires a shift in mindset from "how do I build this?" to "how do I build the team that builds this?" You must demonstrate that you can scale yourself through others while retaining enough technical depth to challenge decisions and guide architecture.

Focus your preparation on these key evaluation criteria:

People Management & Mentorship – 2–3 sentences describing: You must demonstrate a proven ability to grow engineers, handle performance issues, and retain top talent. Interviewers will look for specific examples of how you have coached individuals through career milestones or navigated difficult interpersonal conflicts.

Technical Stewardship – 2–3 sentences describing: While you may not code daily, Datadog expects EMs to have a strong background in distributed systems or modern software architecture. You will be evaluated on your ability to facilitate technical debates, manage technical debt, and ensure operational excellence.

Execution & Delivery – 2–3 sentences describing: This measures how you translate vague requirements into shippable software. You need to show how you prioritize work, manage stakeholder expectations, and maintain velocity without burning out your team.

Culture & Values – 2–3 sentences describing: Datadog prides itself on a culture of humility, transparency, and collaboration. You will be assessed on your ability to leave your ego at the door, learn from incidents (post-mortem culture), and foster an inclusive environment.

3. Interview Process Overview

The interview process for an Engineering Manager at Datadog is widely regarded as organized, transparent, and well-guided. Candidates consistently report that the recruitment team is highly involved, offering detailed explanations of each step and providing qualitative feedback. Unlike chaotic processes elsewhere, you can expect a structured journey where your time is respected, and the expectations for each round are made clear upfront.

Generally, the process begins with a Recruiter Screen, followed by a Hiring Manager Screen (often a Director or VP of Engineering). If successful, you will move to a "Virtual Onsite" or panel stage. This stage is rigorous but manageable, typically consisting of multiple sessions focusing on different competencies: People Management, Technical Architecture/System Design, and Career/Experience Deep Dives. The process is designed to validate your seniority—candidates are carefully assessed against specific levels (e.g., M1, M2), so ensuring your experience aligns with the target level is vital.

The timeline above illustrates a streamlined flow from initial contact to final decision. Use this visual to plan your energy; the "Panel / Onsite" stage is the most intensive part of the process, often involving back-to-back 30–45 minute sessions. Note that while the process is supportive, the bar is high—feedback indicates that appearing "too junior" or lacking specific management depth can be a blocker, even if your technical skills are strong.

4. Deep Dive into Evaluation Areas

To succeed, you must prepare specifically for the distinct "hats" you will wear during the interview loop. Datadog separates these concerns to ensure a holistic view of your capabilities.

People Management & Leadership

This is the core of the interview. You need to prove you are a manager, not just a senior engineer who approves pull requests. Interviewers will dig into your philosophy on leadership and your history of handling "people problems."

Be ready to go over:

• Performance Management – How you identify underperformance, structure Performance Improvement Plans (PIPs), and handle terminations if necessary.
• Career Development – How you identify high-potential engineers and support their promotion paths.
• Conflict Resolution – Mediating disputes between engineers or between engineering and product.
• Recruiting Strategy – How you source, interview, and close candidates in a competitive market.

Example questions or scenarios:

• "Tell me about a time you had to manage a low performer. What was the outcome?"
• "How do you handle a situation where two senior engineers disagree on a technical approach?"
• "Describe a time you had to deliver bad news to your team."

System Design & Technical Judgment

Even as a manager, you cannot treat the system as a "black box." You will face a System Design round where you are expected to drive the high-level architecture of a complex system.

Be ready to go over:

• Scalability & Reliability – Designing systems that handle high throughput and are fault-tolerant (essential for Datadog’s domain).
• Observability – How you would monitor the system you just designed (metrics, logs, traces).
• Trade-offs – Choosing between consistency and availability, or SQL vs. NoSQL, and justifying the decision.

Example questions or scenarios:

• "Design a distributed rate limiter."
• "How would you architect a system to ingest millions of log lines per second?"
• "Your team wants to rewrite a legacy service in a new language. How do you evaluate this request?"

Project Management & Execution

This area tests your ability to get things done. You will need to explain how you run your team day-to-day and how you ensure delivery.

Be ready to go over:

• Agile Methodologies – Your preferred flavor of Agile (Scrum, Kanban) and why it works for you.
• Prioritization – Balancing feature work, bug fixes, and technical debt.
• Stakeholder Management – Managing expectations with Product Managers and upper management.

Example questions or scenarios:

• "The product roadmap is aggressive, but your team is drowning in technical debt. How do you handle this?"
• "Tell me about a project that was behind schedule. How did you get it back on track?"

The word cloud above highlights the most frequently discussed themes in Datadog EM interviews. Notice the prominence of terms like "Team," "Performance," "System," and "Feedback." This indicates that while technical competence is the baseline, your ability to articulate how you build and maintain healthy teams is the primary differentiator.

5. Key Responsibilities

As an Engineering Manager at Datadog, your daily reality involves a dynamic mix of strategic planning and tactical support. You are the primary owner of your team's health and delivery.

You will spend a significant portion of your time collaborating with Product Managers to define the roadmap. This isn't just about accepting requirements; it's about negotiating scope, estimating effort, and ensuring that what is being built is technically feasible and sustainable. You will act as a shield for your team, protecting their focus time from external distractions while ensuring transparency with the rest of the organization regarding progress and blockers.

Simultaneously, you are responsible for organizational growth. Datadog is in a phase of rapid scaling, so you will be heavily involved in recruiting—reviewing resumes, conducting interviews, and selling the company vision to prospective hires. Once they join, you are responsible for their onboarding and continuous career coaching. You will drive the engineering culture by encouraging best practices, code reviews, and participation in post-mortems, ensuring that the team learns from every incident.

6. Role Requirements & Qualifications

Datadog looks for a specific blend of technical roots and management branches. You must be credible to engineers while being effective as a leader.

• Technical Background – You typically need a strong background in software engineering (backend, frontend, or infrastructure). Experience with Go, Python, Java, or Kubernetes is highly relevant, as is experience with cloud providers (AWS, GCP, Azure).

• Management Experience – For an M1 role, you generally need 1–2+ years of formal management experience. For M2 and above, the expectation is significantly higher, often requiring experience managing managers.

• Distributed Systems Knowledge – Experience working on high-scale, high-availability systems is a major plus. Understanding the challenges of microservices and data consistency is often required.

• Communication Skills – You must be able to articulate complex technical concepts to non-technical stakeholders and convey organizational context to your engineers.

• Must-have skills – People management (hiring/firing/growth), Agile delivery, technical architecture review, strong written and verbal communication.

• Nice-to-have skills – Experience in the observability/monitoring domain, open-source contributions, experience managing remote/distributed teams.

8. Frequently Asked Questions

Q: Is there a live coding round for Engineering Managers? Generally, no. The technical rounds for EMs focus on System Design and Architecture rather than LeetCode-style algorithms. However, you should be comfortable reading code and discussing logic at a high level.

Q: How long does the process take? The process is usually efficient. Candidates report timelines ranging from 3 to 5 weeks from initial screen to final decision. The recruiting team is noted for being "very present" and keeping candidates updated.

Q: What is the work culture like regarding location? Datadog has major hubs in New York, Paris, Dublin, and other locations. They support a hybrid model. The interview process is often coordinated across time zones (e.g., HR in the US, interviewers in Europe), so flexibility is helpful.

Q: How difficult is the interview? It is rated as Medium to Hard. The difficulty comes from the breadth of topics—you need to be equally strong in soft skills and technical systems. The "Hard" rating often stems from the depth of probing questions regarding past management experiences.

Q: What if I am rejected? Datadog is known for providing helpful feedback at the end of the process, which is rare in the industry. Use this to refine your skills for future opportunities; many candidates re-apply successfully later.

9. Other General Tips

• Know the Product: Datadog builds tools for engineers. Spend time understanding what APM, Logs, and Infrastructure monitoring actually do. If you can speak the language of observability, you will build instant rapport.
• Be Honest About Failures: When asked about mistakes, do not give a "humble brag." Share a real failure, take ownership, and explain the specific lessons learned. This shows maturity and confidence.
• Structure Your Answers: Use the STAR method (Situation, Task, Action, Result) for behavioral questions. EMs are expected to be clear communicators; rambling answers are a red flag.
• Prepare Questions for Them: You will have time to ask questions. Ask about the team's on-call load, their current technical debt challenges, or how the company maintains culture while scaling. This shows you are evaluating them as a serious partner.
