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
Fundamentals
Explain the basics and the key terms in your own words.
- 2
Applied
Use it on a real task, the way the job does.
- 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.
