Interview Protocol

Introduction (5 minutes)

"Thank you for taking the time to speak with me today. I'm [Your Name] from the Product Team, and I'm conducting research to understand how platform engineers manage and operate the Fawkes platform and how we can make it better.

Purpose: We want to learn about your day-to-day challenges, operational workflows, and what would help you enable developers more effectively. This isn't an evaluation—there are no wrong answers. We're here to learn from your expertise.

Confidentiality: Your responses will be anonymized. We won't share anything that identifies you personally. The insights will inform platform improvements and feature prioritization.

Recording: [If applicable] With your permission, I'd like to record this session for note-taking purposes only. The recording will be deleted after we transcribe it. Are you comfortable with that?

Format: I'll ask you questions about your workflows, challenges, and how you support developers. Feel free to share examples, show me dashboards or tools you use, or even demonstrate challenges you face. We have about 45-60 minutes.

Questions?: Do you have any questions before we start?"

  • Shared concerns about reliability or scale
  • Common automation opportunities

Tips for Effective Interviewing

Do's ✅

  • Respect their expertise: Platform engineers are technical experts—value their insights
  • Ask for demonstrations: "Can you show me your monitoring dashboard?"
  • Explore trade-offs: Understand their decision-making process
  • Dig into incidents: Post-mortems reveal valuable insights
  • Understand priorities: What do they optimize for? (reliability, speed, cost)
  • Ask about metrics: What DORA metrics or SLOs do they track?
  • Explore team dynamics: How do they work with security, networking, etc.?

Don'ts ❌

  • Don't assume they know everything: Some areas may be owned by others
  • Don't skip emotional responses: Frustration and pride are valuable signals
  • Don't ignore technical details: Deep dive into architecture and tools
  • Don't overlook on-call burden: This is often a major pain point
  • Don't forget the human element: Platform engineers care deeply about enabling developers
  • Don't dismiss "boring" work: Maintenance and operations are critical
  • Don't focus only on problems: Understand what works well too

Effective Follow-up Questions

  • "Can you show me an example in your monitoring system?"
  • "What would you do differently if you could start over?"
  • "How does this impact developer productivity?"
  • "What metrics tell you this is a problem?"
  • "Who else is affected by this issue?"
  • "What's the cost of not fixing this?"
  • "How do other platforms handle this?"
  • "What would the ideal workflow look like?"
