The three steps

How each skill is tested

Questions get harder as you get better at a skill. A step counts once you answer a question at that level well, in an interview or a practice session. Nobody ticks a step off: you show it.

  1. 1

    Fundamentals

    Explain the basics and the key terms in your own words.

  2. 2

    Applied

    Use it on a real task, the way the job does.

  3. 3

    Scenario

    Decide in a realistic situation and explain the trade-offs.

Freshers start at the fundamentals. With 1 to 6 years of experience, questions start at the applied step.
