What interviewers look for

  • Clear STAR structure in every answer
  • Specific, authentic examples
  • Alignment with Do What's Right, Respect Others, Perform With Excellence
  • Technical competence demonstrated through examples
  • Integrity and authenticity

Focus areas to practise

  • Tell me about a complex project you led
  • Describe how you resolved a technical challenge
  • Give an example of doing the right thing under pressure
  • How have you demonstrated excellence in your work?
  • Structure EVERY answer as STAR (Situation, Task, Action, Result)
  • Prepare 8+ stories covering different competencies
  • Be authentic - don't fabricate or exaggerate
  • Ensure your video/Teams/Zoom setup is flawless
Technical Panel (Engineering Roles)

For engineering roles: deeper technical discussion assessing domain expertise, system design thinking, and engineering judgement.

Format: Technical deep-dive with engineering panel, 45-60 minutes

What interviewers look for

  • Deep domain expertise
  • System-level thinking
  • Engineering judgement and trade-off analysis
  • Innovation and problem-solving
  • Clear communication of complex ideas

Focus areas to practise

  • System architecture decisions
  • Technical problem-solving methodology
