The Danger Zone: Top Reasons Candidates Fail

Based on our database of EY interview outcomes, avoid these common traps:

Recommending a centralized solution without considering local data privacy regulations
Assuming all integrations should be real-time without considering system load
Ignoring the impact of cross-region latency on user experience
Focusing only on technical speed rather than the financial and risk profile of the migration

Test Yourself: EY Interview Questions

Three questions from the EY bank.

Type · case-study

A retail client is experiencing significant latency in their e-commerce checkout process during peak traffic periods. They suspect the bottleneck is their legacy database, but the IT team is hesitant to migrate to a new engine. How would you design a diagnostic framework to isolate the latency source without disrupting the current production environment?

Type · behavioral

STAR

Describe a time you had to deliver a difficult technical recommendation that contradicted the client's preferred vendor choice. How did you maintain the relationship while ensuring the client made the right architectural decision?

Type · communication

You have identified a critical security vulnerability in a client's proposed architecture just days before a major milestone. How do you communicate this to a non-technical executive sponsor who is under pressure to meet the launch date?

A multinational client is struggling with data silos across their regional business units, preventing accurate global reporting. How would you evaluate the trade-offs between implementing a centralized global data platform versus maintaining regional autonomy with standardized API integrations?

When designing an enterprise integration layer for a client moving from on-premise systems to a hybrid cloud environment, what criteria do you use to decide between synchronous REST APIs and asynchronous event-driven messaging?
5
Type · architecture

Client Presentation

6
Type · communication

7
Type · communication
You are presenting a cloud migration roadmap to a client's Board of Directors. One board member argues that keeping operations on-premise is inherently safer and cheaper in the long run. How do you respond to this skepticism while maintaining credibility?
