This opening question aims to verify that you have solid experience working with large, complex systems comparable to EY’s global IT infrastructure Emphasize your knowledge of identifying business needs, designing scalable solutions, and optimizing existing systems across an entire enterprise

Sample Answer Throughout my career I have led numerous enterprise-level system analysis and design projects. For example I spearheaded the cloud migration of a Fortune 500 firm’s antiquated on-premise servers to a robust AWS-based system. This complex initiative involved extensive planning to ensure seamless integration and uninterrupted business operations during the transition. I also re-designed the IT infrastructure of a multinational bank to enhance security, efficiency, and scalability as the company rapidly expanded to new markets. Based on your firm’s global footprint, I am confident I can apply my expertise to support EY’s enterprise-wide objectives.

2. What strategies would you employ to ensure the alignment of IT systems with EY’s business objectives?

This question tests your ability to bridge the gap between technical capabilities and business goals. EY wants to see that you can deliver solutions tailored to their specific organizational needs and growth strategies.

Sample Answer: My approach for ensuring proper alignment between systems and business objectives focuses on three key strategies:

  • Maintaining constant communication with stakeholders across the organization to fully understand EY’s goals and pain points. This allows me to design technology that directly enables your business priorities.

  • Conducting regular reviews of systems and tech roadmaps to confirm they continue meeting evolving business needs. I would recommend bi-annual reviews as EY rapidly scales and enters new markets.

  • Proactively researching industry trends and emerging technologies that may benefit EY’s business aims. For instance, leveraging AI and automation solutions to increase efficiency and insights in auditing and consulting services.

Through this collaborative strategy, I can provide technology capabilities that directly empower EY’s business success and company vision.

Sample Answer: In my last role, I utilized statistical modeling tools to analyze customer churn data. By applying regression analysis and identifying high-risk variables, I developed a predictive model for customer retention. This model enabled proactive retention campaigns targeting customers most likely to churn. Over a 6-month period, these personalized campaigns reduced churn rate by 22%. This example highlights my ability to leverage data modeling techniques to directly inform business process optimization. Based on EY’s vast datasets, I’m confident I can apply similar methods to support improved efficiency and decision-making across the firm.

4. Please explain how you would approach troubleshooting a major system failure.

This question tests your methodology and poise when facing high-pressure system issues. Demonstrate a calm, structured approach focused on restoring services quickly and safely.

Sample Answer: In the event of a major system failure, I would follow a rigorous, timely troubleshooting methodology:

  • Pinpoint failure – Review system logs/metrics thoroughly to identify the root cause, flawed component, and upstream effects.

  • Contain damage – Isolate the failure and halt related processes to prevent further issues from arising.

  • Coordinate response – Work closely with relevant teams and management to coordinate an effective response plan.

  • Enact solution – Leverage backups, redundancies, patches, and expert support to safely restore full functionality.

  • Debrief – Document the incident thoroughly for future review and prevention.

Throughout the process I would provide frequent status updates to stakeholders and focus intently on restoring key services as soon as possible. My even-keeled approach allows me to effectively manage high-stakes system issues.

  • Localization – All sites would have multi-language interfaces tailored to regional users.

  • Global security standards – Unified cybersecurity protocols applied firm-wide to ensure seamless, safe operations.

  • Rolling updates – New system updates would be incrementally deployed region-by-region to catch any localization issues.

  • Remote access – Staff worldwide could securely access EY systems and data resources remotely as needed.

With these solutions in place, I can deliver a streamlined technology infrastructure that performs consistently for EY across the globe.
