The Danger Zone: Top Reasons Candidates Fail

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

Crashing on missing keys instead of using defaults or returning null.
Choosing inappropriate technologies for real-time alerting.
Focusing solely on personal career goals without connecting them to company objectives.
Incorrectly handling the sorting and tie-breaking logic for plans with the same price.

Test Yourself: Real Cortea Questions

Three real prompts pulled from our database.

Type · coding

Write a function to parse a complex, nested JSON configuration file used for setting up SaaS application integrations. The function should handle missing keys gracefully and allow for default values to be provided. Ensure the output is a clean, validated data structure.

Type · debugging

Here is a Python function that's supposed to calculate the total monthly cost of SaaS subscriptions for a given user, considering discounts for annual payments. It's producing incorrect results for some users. Debug and fix the code.
