The Danger Zone: Top Reasons Candidates Fail

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

  • Blaming the other party without acknowledging their perspective.
  • Inefficiently iterating through all pairs of interests without optimization.
  • Failing to handle cases where closing brackets appear before opening brackets.
  • Choosing a single point of failure in the notification delivery pipeline.

Test Yourself: Real Tinder Questions

Three real prompts pulled from our database.

Type · Behavioral

Tell me about a time you had to work with a difficult stakeholder or team member. How did you approach the situation, and what was the outcome?

Type · Algorithmic

Implement a function to determine if a given string of parentheses, brackets, and braces is valid (i.e., all open brackets are closed in the correct order).

Type · Debugging

A user reports that their match list is not updating correctly, showing old matches or missing new ones. Here is a snippet of the code responsible for fetching and displaying matches. Debug and fix the issue.
