Test Yourself: Real BPER Banca Questions
Three real prompts pulled from our database.
Type · algorithmic
Design a function that takes a list of financial instruments (e.g., stocks, bonds) with their current prices and a target portfolio value. The function should return a list of instruments and their quantities that best approximate the target value, minimizing the difference. Assume fractional quantities are allowed.
Type · past-experience
Describe a situation where you had to collaborate with non-technical stakeholders (e.g., product managers, business analysts) at BPER Banca to deliver a feature. How did you ensure clear communication and alignment?
