Example questions or scenarios:

• "Walk me through how you configured the New Relic agent on your demo application during the take-home challenge."
• "If an application is running but no APM data is showing up in the UI, what are the first three things you would check?"

Customer Scenario Simulation & Presentation

In this stage, you will often be asked to present a case study or role-play a customer scenario. This tests your ability to translate technical findings into actionable business value.

Be ready to go over:

• Structured Presentations – Delivering a clear, concise technical presentation to a panel representing different customer stakeholders.
• De-escalation Techniques – Managing difficult questions from a "frustrated customer" during a mock scenario.
• Value Realization – Explaining how solving a technical performance issue directly impacts business metrics like user conversion or system uptime.

Example questions or scenarios:

• "Present your findings from the take-home application setup as if you were advising a customer's engineering lead on how to optimize their app."
• "How would you respond if a customer executive interrupts your presentation to say they don't see the ROI of our platform?"

Behavioral & Value Alignment

New Relic places a strong emphasis on team dynamics and culture fit. This area evaluates how you handle challenges, collaborate with peers, and align with the company's core values.

Be ready to go over:
