What is an OT (Online Testing)?

Online Testing (OT) is an assessment tool widely used in graduate hiring to screen candidates’ cognitive ability, logical reasoning and workplace judgement before interviews. Firms such as Goldman Sachs, McKinsey and ByteDance use OTs as a first-round filter.

Common OT question types

  • Numerical reasoning: how well you read charts, calculate and reason with data
  • Inductive reasoning: how well you spot patterns and reason logically
  • Situational judgement test: decision-making and professionalism in workplace scenarios

How to prepare for an OT?

The key is practice and familiarity with the formats. Start with the free diagnostic above, then cross-practise with commercial question banks.
