Test Yourself: Real Allica Bank Questions
Three real prompts pulled from our database.
Type · Past Experience
Tell me about a time you had to influence a stakeholder (e.g., engineer, designer, executive) who had a different opinion or priority than you. How did you approach it, and what was the outcome?
Type · Data Structures & Algorithms
Implement a function to detect potential fraudulent transactions. A transaction is considered potentially fraudulent if it's more than 3 standard deviations away from the average transaction amount for that customer in the last 24 hours. Assume you have access to historical transaction data for each customer.
