Test Yourself: Real bunch 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, marketing) who had a different opinion on a product decision. How did you approach it, and what was the outcome?

Type · Influence

Describe a situation where you had to persuade a skeptical colleague or client to adopt your point of view.

Type · Algorithmic

Given a list of transactions, each with a timestamp, amount, and user ID, write a function to calculate the total amount spent by each user within a given time window (e.g., the last 24 hours).
