Agile Methodologies Interview Questions for a Technical Lead
Overview
Section titled “Overview”For a Technical Lead with 9+ years of experience, Agile interview questions usually focus less on definitions and more on:
- Real-world project situations
- Team coordination
- Delivery risks
- Estimation
- Technical decisions
- Technical debt
- Stakeholder communication
- Quality and engineering practices
The following questions and answers are structured for a Java/Spring Boot + React Technical Lead interview.
1. Agile Fundamentals
Section titled “1. Agile Fundamentals”1. What is Agile?
Section titled “1. What is Agile?”Answer:
Agile is an iterative software development approach where work is delivered in small increments, with continuous customer feedback and adaptation. It emphasizes collaboration, working software, responding to change, and delivering business value frequently.
2. What are the Agile Manifesto principles?
Section titled “2. What are the Agile Manifesto principles?”Answer:
The four core values are:
- Individuals and interactions over processes and tools
- Working software over comprehensive documentation
- Customer collaboration over contract negotiation
- Responding to change over following a plan
3. Agile vs Waterfall?
Section titled “3. Agile vs Waterfall?”Answer:
Waterfall follows a sequential approach where requirements are largely finalized upfront. Agile works incrementally, allowing requirements and priorities to evolve based on feedback and business needs.
4. What Agile methodology have you worked with?
Section titled “4. What Agile methodology have you worked with?”Answer:
“I have primarily worked with Scrum. We work in short sprints, typically two weeks, with sprint planning, daily stand-ups, refinement, review, and retrospective. As a technical lead, I focus on technical design, breaking down stories, identifying dependencies and risks, and supporting the team in delivering the sprint goal.”
2. Scrum Questions
Section titled “2. Scrum Questions”5. What are the roles in Scrum?
Section titled “5. What are the roles in Scrum?”Answer:
- Product Owner – owns product vision, backlog and prioritization.
- Scrum Master – facilitates Scrum and removes process impediments.
- Development Team – designs, develops, tests and delivers the increment.
- Technical Lead – not an official Scrum role, but typically provides technical direction, architecture guidance, code quality and mentoring.
6. What happens during Sprint Planning?
Section titled “6. What happens during Sprint Planning?”Answer:
The team reviews prioritized backlog items, clarifies requirements, estimates effort, identifies dependencies and selects work that can realistically be completed during the sprint. The team then defines a Sprint Goal.
7. What is a Sprint Goal?
Section titled “7. What is a Sprint Goal?”Answer:
A Sprint Goal is the primary objective the team wants to achieve during a sprint. It provides focus and helps the team make decisions if priorities or circumstances change during the sprint.
8. What is a Product Backlog?
Section titled “8. What is a Product Backlog?”Answer:
The Product Backlog is an ordered list of features, enhancements, bugs, technical work and other items required for the product. The Product Owner is primarily responsible for its prioritization.
9. What is backlog refinement?
Section titled “9. What is backlog refinement?”Answer:
Backlog refinement is the process of preparing upcoming stories by clarifying requirements, identifying acceptance criteria, splitting large stories, discussing technical dependencies and estimating effort.
3. Technical Lead Scenario Questions
Section titled “3. Technical Lead Scenario Questions”10. A developer says a story cannot be completed within the sprint. What do you do?
Section titled “10. A developer says a story cannot be completed within the sprint. What do you do?”Answer:
First, I understand the reason—technical complexity, unclear requirements, dependency or incorrect estimation. I discuss options with the developer and team, try to remove blockers or split the story if appropriate, and communicate the risk to the Scrum Master and Product Owner early rather than waiting until the end of the sprint.
11. The team consistently misses sprint commitments. How would you handle it?
Section titled “11. The team consistently misses sprint commitments. How would you handle it?”Answer:
I would analyze historical sprint data and identify whether the issue is overcommitment, poor estimation, dependencies, production support, unclear requirements or technical debt. I would work with the team to improve estimation and capacity planning and address the root cause rather than simply asking the team to work harder.
12. Product Owner adds a critical requirement in the middle of a sprint. What do you do?
Section titled “12. Product Owner adds a critical requirement in the middle of a sprint. What do you do?”Answer:
I would first understand its urgency and business impact. If it genuinely cannot wait, I would discuss the impact with the Product Owner and Scrum Master and determine whether existing sprint scope needs to be removed or the sprint goal needs to change. I would avoid simply adding work without considering capacity.
13. How do you handle technical debt in Agile?
Section titled “13. How do you handle technical debt in Agile?”Answer:
I make technical debt visible in the backlog and quantify its impact where possible. I work with the Product Owner to prioritize important technical debt alongside feature work, especially when it affects performance, reliability, security or development velocity.
14. How do you ensure technical quality while working in short sprints?
Section titled “14. How do you ensure technical quality while working in short sprints?”Answer:
I establish engineering practices such as code reviews, automated unit and integration testing, static code analysis, CI/CD checks and Definition of Done criteria. I also ensure that architecture and technical discussions happen early during refinement rather than at the end of the sprint.
4. Estimation Questions
Section titled “4. Estimation Questions”15. What is Story Point estimation?
Section titled “15. What is Story Point estimation?”Answer:
Story points represent the relative effort and complexity of a user story. They generally consider factors such as complexity, amount of work, uncertainty and dependencies rather than directly representing hours.
16. Story points vs hours?
Section titled “16. Story points vs hours?”Answer:
Hours estimate absolute effort, whereas story points provide relative estimation. For example, if Story A is estimated as 5 points and Story B as 10 points, B is considered roughly twice as complex or demanding relative to A.
17. What is Planning Poker?
Section titled “17. What is Planning Poker?”Answer:
Planning Poker is a collaborative estimation technique where team members independently select story-point values and then discuss differences before reaching a consensus. It helps avoid one person’s estimate influencing everyone else.
18. What is velocity?
Section titled “18. What is velocity?”Answer:
Velocity is the amount of story-point work a team actually completes in a sprint. Historical velocity can help with forecasting, but it should not be treated as a performance target for individual developers.
5. Definition of Done / Acceptance Criteria
Section titled “5. Definition of Done / Acceptance Criteria”19. What is Definition of Done?
Section titled “19. What is Definition of Done?”Answer:
Definition of Done is the agreed set of criteria that must be satisfied for a story or increment to be considered complete. It may include coding, code review, unit testing, integration testing, security checks, documentation and successful deployment to the required environment.
20. Definition of Done vs Acceptance Criteria?
Section titled “20. Definition of Done vs Acceptance Criteria?”Answer:
Acceptance Criteria are specific to a particular user story and define what the functionality must achieve.
Definition of Done applies generally to all applicable stories and defines the quality/completion standards.
Example:
Acceptance criterion: “User should receive an email after successful registration.”
Definition of Done: “Code reviewed, unit tests passed, integration tests passed and deployed successfully.”
6. Daily Scrum / Team Management
Section titled “6. Daily Scrum / Team Management”21. What do you discuss in Daily Scrum?
Section titled “21. What do you discuss in Daily Scrum?”Answer:
The focus should be on progress toward the Sprint Goal, what is being worked on, upcoming work and blockers. As a technical lead, I pay particular attention to technical dependencies and risks that could affect sprint delivery.
22. One developer dominates technical discussions. What do you do?
Section titled “22. One developer dominates technical discussions. What do you do?”Answer:
I would ensure everyone gets an opportunity to contribute and deliberately ask quieter team members for their views. If necessary, I would take detailed technical discussions offline with the relevant people while keeping the broader team aligned.
23. Two developers strongly disagree about an architecture decision. How do you handle it?
Section titled “23. Two developers strongly disagree about an architecture decision. How do you handle it?”Answer:
I would bring the discussion back to objective criteria such as scalability, maintainability, performance, security and business requirements. If necessary, we can create a small proof of concept and compare the approaches using measurable results before making the decision.
7. Sprint Retrospective
Section titled “7. Sprint Retrospective”24. What happens in a retrospective?
Section titled “24. What happens in a retrospective?”Answer:
The team discusses:
- What went well
- What did not go well
- What can be improved
- Concrete action items
As a lead, I ensure the retrospective results in actionable improvements, rather than becoming just a discussion about problems.
25. The same issue keeps appearing in retrospectives. What would you do?
Section titled “25. The same issue keeps appearing in retrospectives. What would you do?”Answer:
I would identify the root cause using techniques such as 5 Whys and assign a specific improvement action with an owner and target date. In the next retrospective, we should review whether the action actually solved the problem.
8. Agile Metrics
Section titled “8. Agile Metrics”26. What Agile metrics do you track?
Section titled “26. What Agile metrics do you track?”Answer:
Depending on the project, I would track:
- Sprint velocity
- Sprint completion rate
- Lead time
- Cycle time
- Defect trends
- Escaped defects
- Deployment frequency
- Build/test failure rate
- Production incidents
- Cumulative flow
I avoid using metrics simply to rank individual developers.
27. What is a burndown chart?
Section titled “27. What is a burndown chart?”Answer:
A burndown chart shows the amount of remaining work against time during a sprint or release. It helps identify whether the team is progressing toward completing planned work.
28. What is lead time vs cycle time?
Section titled “28. What is lead time vs cycle time?”Answer:
Lead time: Time from when work is requested until it is delivered.
Cycle time: Time from when active development starts until the work is completed.
9. Difficult Technical Lead Scenarios
Section titled “9. Difficult Technical Lead Scenarios”29. Production issue occurs in the middle of a sprint. What do you do?
Section titled “29. Production issue occurs in the middle of a sprint. What do you do?”Answer:
First, I assess severity and business impact. For a critical production issue, we prioritize restoring service and communicate the impact to stakeholders. After stabilization, we perform RCA and add appropriate corrective/preventive work to the backlog.
30. Your team has too many dependencies on another team. How do you manage them?
Section titled “30. Your team has too many dependencies on another team. How do you manage them?”Answer:
I identify dependencies during refinement and sprint planning rather than discovering them during implementation. I establish early communication with the dependent team, agree on timelines/interfaces and, where possible, reduce coupling through contracts, mocks, asynchronous processing or API versioning.
31. Business wants faster delivery, but developers say the architecture needs improvement. What do you do?
Section titled “31. Business wants faster delivery, but developers say the architecture needs improvement. What do you do?”Answer:
I explain the technical risks in terms of business impact—future delays, outages, scalability or maintenance cost. Instead of blocking delivery unnecessarily, I look for an incremental approach where we deliver business value while addressing the most critical architectural concerns.
32. How do you handle a low-performing team member?
Section titled “32. How do you handle a low-performing team member?”Answer:
I first try to understand whether the problem is technical knowledge, unclear expectations, communication, motivation or external factors. I provide specific feedback, mentoring and measurable expectations, and track improvement over time. If the issue continues, I involve the appropriate manager through the established process.
10. Agile + Technical Architecture
Section titled “10. Agile + Technical Architecture”33. How do you perform architecture in an Agile environment?
Section titled “33. How do you perform architecture in an Agile environment?”Answer:
I prefer evolutionary architecture rather than attempting to design every detail upfront. We establish important architectural decisions early, document key ADRs, identify scalability/security concerns and evolve the design as requirements become clearer.
34. Does Agile mean “no documentation”?
Section titled “34. Does Agile mean “no documentation”?”Answer:
No. Agile values working software, but it does not eliminate documentation. We maintain documentation that provides real value, such as API contracts, architecture diagrams, ADRs, deployment procedures and operational documentation.
35. How do you balance feature development and refactoring?
Section titled “35. How do you balance feature development and refactoring?”Answer:
I identify refactoring opportunities during development and make significant technical debt visible in the backlog. For critical issues affecting reliability, security or scalability, I work with the Product Owner to prioritize them rather than continuously postponing them.
