The Danger Zone: Top Reasons Candidates Fail

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

  • Lack of clear request/response formats.
  • Focusing on blaming others for the problem.
  • Describing a situation that was clearly within their job scope.
  • Describing manipulation rather than genuine influence.

Test Yourself: Real Tebi Questions

Three real prompts pulled from our database.

Type · Ownership

Tell me about a time you took ownership of a challenging sales situation that wasn't explicitly part of your job description. What was the situation, what did you do, and what was the outcome?

Type · Data Structures

Design a data structure that can efficiently store and retrieve payment transaction data, supporting operations like adding a transaction, retrieving transactions by user ID, and retrieving transactions within a date range. Discuss the trade-offs.

Type · Algorithmic

Given a list of transaction timestamps for a fintech platform, write a function to find the number of transactions within any given one-hour window. Optimize for efficiency.
