Behavioral Skills & Interviews

Behavioral interviews assess your soft skills, cultural fit, and how you handle real-world situations. For Platform/SRE/DevOps roles, expect questions about incidents, collaboration, and technical leadership.

The STAR Method​

Always structure your answers using STAR:

  • Situation: Set the context
  • Task: Explain what needed to be done
  • Action: Describe what YOU specifically did
  • Result: Share the outcome and what you learned

Common Behavioral Questions by Category​

1. Incident Management & Problem Solving​

"Tell me about a time you handled a critical production incident"

Example STAR Answer:

  • S: Our payment processing system went down during Black Friday, affecting $2M/hour in transactions
  • T: As the on-call SRE, I needed to restore service quickly while coordinating with multiple teams
  • A: I immediately started incident command, assigned roles, and began systematic troubleshooting. Found a database connection pool exhaustion issue. Implemented temporary fix in 15 minutes, then led post-mortem
  • R: Reduced downtime to 22 minutes (saved $1.3M in losses), created runbook for similar issues, implemented connection pool monitoring

Other Common Questions:

  • Describe your most challenging debugging experience
  • How do you handle incidents when you don't know the root cause?
  • Tell me about a time you prevented a major outage
  • Share an example of learning from failure

"Describe a time you had to convince developers to adopt a new practice"

Example STAR Answer:

  • S: Developers were resistant to implementing proper health checks in microservices
  • T: Needed to improve service reliability without creating developer friction
  • A: Created a simple health check library, demonstrated value with metrics showing 40% faster incident detection, offered hands-on workshops

  • T: Select solution balancing features, team expertise, and long-term costs
  • A: Conducted PoC for both, created decision matrix, consulted with teams, considered hiring challenges
  • R: Chose Kubernetes despite steeper learning curve, saved $300K/year, became recruiting advantage

Other Common Questions:

  • Describe balancing technical debt vs. new features
  • Share an example of planning for scale

5. Process Improvement & Innovation​

"Give an example of improving an inefficient process"

Example STAR Answer:

  • S: Deployments taking 4 hours with frequent failures
  • T: Reduce deployment time and improve reliability
  • A: Analyzed bottlenecks, implemented blue-green deployments, automated testing, created deployment dashboard
  • R: Reduced deployment time to 20 minutes, 95% success rate, developers self-serve deployments

Other Common Questions:

  • How do you identify areas for improvement?
  • Describe implementing a new tool/process
  • Tell me about automating a manual task
  • Share an innovation you're proud of

6. Conflict Resolution​

"Tell me about a conflict with a coworker"

Example STAR Answer:

  • S: Senior developer insisted on keeping monolithic architecture despite reliability issues
  • T: Find compromise while improving system reliability
  • A: Listened to concerns, proposed gradual migration starting with problem areas, showed data on benefits
  • R: Agreed on hybrid approach, improved reliability 50%, maintained good relationship

Other Common Questions:

  • How do you handle competing priorities?
  • Describe disagreeing with your manager

  • Mentoring others
  • Strategic thinking
  • Stakeholder management

Staff/Principal Level​

  • Organizational impact

  • Executive communication

Red Flags to Avoid​

  1. Blaming Others: Always focus on your actions and learnings
  2. No Specific Examples: Have concrete stories ready
  3. Not Listening: Answer the question asked
  4. No Growth Shown: Demonstrate learning from experiences
  5. Negative Attitude: Stay positive even about challenges

Questions to Prepare​

Have 2-3 stories ready for each:

  • Major incident handled
  • Process improvement led
  • Difficult technical decision
  • Cross-team collaboration
  • Mentoring/leadership example
  • Learning from failure
  • Innovation/creative solution
  • Conflict resolution

Practice Framework​

1. Build Your Story Bank​

Create 10-15 STAR stories covering various scenarios

  • Time yourself (aim for 2-3 minutes per answer)
  • Record yourself
  • Get feedback from peers

3. Adapt Stories​

One story can answer multiple questions with different emphasis

4. Mock Interviews​

  • Use Pramp or interviewing.io
  • Practice with friends in similar roles
  • Join online communities for practice partners

  • Monitoring/Alerting: Philosophy on noise vs. coverage
  • Capacity Planning: Predicting and preparing for growth
  • Post-Mortems: Blameless culture and learning
  • Chaos Engineering: Intentional failure injection
  • Tool Building: Creating vs. buying solutions

Final Tips​

  1. Be Authentic: Use real examples, not hypothetical
