Practice real frameworks

Hands-on Prompting & Evaluation exercises that mirror real engineering work — from core fundamentals to the patterns interviewers actually probe. Every challenge is graded automatically and mapped to a skill below.

Prompting stops being guesswork once you can measure it. These challenges pair prompt design - instructions, examples, output formats, refusal handling - with the evaluation harness that tells you whether a change helped: test sets, graders, regression runs, and the judgement calls about what counts as correct when more than one answer is.
