How a prep kit worksGrounded workflow
  1. 01

    Add a target role

    Start with your job description and resume.

  2. 02

    Review the evidence

    See what is supported, partial, or not explicitly mentioned.

  3. 03

    Practice with purpose

    Open the next relevant SQL, Python, behavioral, or system-design task.

Your dashboard reuses saved evidence and practice results. It does not generate new content when you open it.
Explainable preparation

Every recommendation has a source.

Data Role Ready keeps role requirements, resume evidence, and practice performance distinct, so you can see why a task is relevant before starting it.

01 · Role requirements

Requirements are extracted from the target job.

02 · Candidate evidence

Resume and confirmed evidence are linked to the role.

03 · Practice selection

The next task is selected from validated kit content.

04 · Practice evidence

Completed attempts build a more useful readiness signal.

Evidence coverage and interview readiness remain separate throughout the workflow.
Adaptive preparation

Always know what to practice next.

Job-specific competency map

Review and correct the skills, evidence, gaps, and weights extracted from your target role.

One clear next task

Practice the highest-value gap instead of choosing among a wall of equal-priority questions.

Evidence-based progress

Deterministic results and rubric feedback update readiness after each graded attempt.

The prep environment

Work through real question context, write an answer, then run or submit when you are ready.

Question context

Use the schema and requirements beside the editor.

  • Structured question prompt
  • Available tables or test cases
  • Role-relevant competency mapping
Write your answer

SQL and Python use the correct workspace for the question.

Run
// Open a question to write and test your answer.
// Results and deterministic checks appear after you run it.

Feedback when requested

Keep control of the learning loop.

Use hints, explanations, and review actions only when you choose them. Saved feedback stays connected to the question and its validated role requirement.
