Team Leadership & Culture Building
At Lambda, engineering managers are expected to be deliberate and empathetic leaders. This area evaluates your ability to grow and mentor a team of high-performing platform engineers and SREs. Interviewers want to see that you can navigate complex team dynamics, handle underperformance constructively, and create an environment where engineers feel supported in their career development.
Be ready to go over:
- Hiring and Scaling – How you identify top talent, structure interviews, and onboard engineers effectively.
- Performance Management – Your approach to regular 1-on-1s, giving actionable feedback, and managing both high performers and those needing improvement.
- Culture and Morale – Techniques for fostering collaboration, technical excellence, and a customer-service mindset within an internal platform team.
- Organizational Improvement – Less common but highly valued is your experience driving broader organizational changes, such as revamping incident response processes or standardizing engineering levels.
Example questions or scenarios:
- "Tell me about a time you inherited a team that was struggling with morale or delivery. What steps did you take to turn it around?"
- "Walk me through your process for managing an engineer who is technically brilliant but struggles with cross-functional collaboration."
- "How do you balance the need to deliver urgent platform features with the ongoing career development and upskilling of your team members?"
Technical Strategy & Platform Engineering
While you may not be writing code every day, you must possess the technical depth to guide your team’s architectural decisions. Lambda relies heavily on AWS, infrastructure as code, and robust CI/CD pipelines. You will be evaluated on your ability to identify gaps in platform posture, drive resolution, and lead the adoption of best practices across the broader engineering organization.
Be ready to go over:
- Cloud Architecture – Deep knowledge of AWS services, scaling strategies, and cost management.
- Infrastructure Automation – Experience expanding platforms using tools like Terraform and Atlantis.
- CI/CD and Workflows – Managing and scaling solutions based on Buildkite, GitHub Actions, or advanced workflow engines like Temporal.
- Self-Service Abstractions – Designing internal tooling that is easy for product engineers to adopt without heavy hand-holding.
Example questions or scenarios:
- "Describe a time you led the design and rollout of a new CI/CD pipeline across multiple engineering teams. How did you drive adoption?"
- "How would you approach designing a self-service infrastructure provisioning system for internal developers using Terraform?"
- "Tell me about a situation where you had to push back on a proposed architecture in an engineering RFC. How did you handle the technical disagreement?"
Execution & Project Management
Delivering reliable platform solutions on schedule is critical to keeping Lambda's product teams moving quickly. This evaluation area focuses on your project management skills, how you prioritize work, and how you manage both internal resources and external vendors.
Be ready to go over:
- Agile and SDLC – How you structure sprints, manage backlog grooming, and ensure quality delivery.
- Prioritization – Balancing technical debt, operational toil, and new feature development.
- Vendor Management – Evaluating, managing, and optimizing costs for SaaS vendors and cloud providers.
- Incident and Escalation Management – How you lead your team through high-severity incidents and conduct blameless post-mortems.
Example questions or scenarios:
- "Walk me through your approach to managing a complex, cross-functional project with competing deadlines. How do you ensure alignment?"
- "Tell me about a time you had to significantly reduce cloud infrastructure spend. What was your strategy, and what were the results?"
- "How do you measure the success and reliability of the platform services your team provides to internal customers?"
Cross-Functional Collaboration
Platform engineering does not happen in a vacuum. You will need to work closely with Lambda product engineering teams to understand their requirements and plan effectively. This area tests your ability to act as an internal consultant, manage stakeholder expectations, and drive alignment across different engineering functions.
Be ready to go over:
- Requirement Gathering – Translating the needs of product teams into scalable platform solutions.
- Stakeholder Alignment – Managing expectations when platform roadmaps conflict with product team timelines.
- Evangelism – Leading the broader engineering organization in the adoption of new workflow and cloud services.
Example questions or scenarios:
- "Tell me about a time you had to deliver a platform capability that multiple teams needed, but they all had slightly different requirements."
- "How do you handle a situation where a product team is demanding a custom infrastructure solution that deviates from your team's technical standards?"
- "Describe your strategy for transitioning an engineering organization from a highly manual deployment process to a fully automated, self-service model."
