Description

Adds an AI Multi-Solution Discovery Challenge that encourages candidates
to find and compare multiple valid solutions to the same interview problem.

Features

  • Initial solution evaluation
  • Alternative solution discovery
  • Time complexity comparison
  • Space complexity comparison
  • Solution trade-off analysis
  • Use-case comparison
  • Adaptive follow-up questions
  • Multi-solution discovery scoring
  • Interactive solution comparison
  • Decision-making guidance

Goal

Help candidates move beyond the first correct solution and develop flexible
problem-solving and technical trade-off reasoning skills.

Summary

Adds AI interview coaching pages for:

  • Multi-solution discovery and solution comparison.
  • Skill-regression monitoring.
  • Ambiguity-handling practice.
  • Solution input-validation coaching.

The multi-solution challenge compares brute-force and hash-map solutions, including complexity, trade-offs, scoring, and decision guidance.

Ready to merge.

Review Change Stack

📝 Walkthrough

Walkthrough

Added four React pages for AI interview preparation. The pages cover skill regression monitoring, ambiguity handling, multi-solution discovery, and solution input validation. Each page includes static coaching content, expandable sections, local interaction state, workflow guidance, and completion feedback.

Changes

AI interview coaching pages

Layer / File(s) Summary
Skill regression monitoring
frontend/src/pages/AIInterviewPreparationSkillRegressionAlert.jsx
Adds skill status metrics, Binary Search regression details, alert controls, maintenance tasks, recommendations, and a regression-detection workflow.
Ambiguity handling practice
frontend/src/pages/AIInterviewQuestionAmbiguityHandlingPractice.jsx
Adds an underspecified interview prompt, selectable ambiguity areas, clarification examples, coaching prompts, recommendations, workflow steps, and evaluation feedback.
Multi-solution discovery challenge
frontend/src/pages/AIInterviewQuestionMultiSolutionDiscoveryChallenge.jsx
Adds a two-sum challenge with brute-force and hash-map solutions, complexity comparisons, solution selection, submission feedback, and score recalculation.
Input validation coaching
frontend/src/pages/IInterviewQuestionSolutionInputValidationCoach.jsx
Adds validation cases, risk metrics, strategy factors, coaching questions, recommendations, workflow steps, and analysis feedback.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 5dafd

The feature adds interactive AI interview practice pages, but one page is currently unreachable and the multi-solution experience can present discovery and scoring results before a candidate submits an evaluated response. This can mislead users and should be corrected before merge; accessibility and default-selection follow-ups also remain.

Expose the control state to assistive technology.

The alert control does not expose whether alerts are enabled. The disclosure controls do not expose whether their content is expanded. Add role="switch" with aria-checked to the alert control. Add aria-expanded to each disclosure control.

Register AIInterviewQuestionAmbiguityHandlingPractice in frontend/src/App.jsx.

The page is not imported or rendered by any route. Direct navigation therefore reaches the catch-all NotFound route. Add the intended path under MainLayout and apply the required access control.

Select the initial solution by default.

Line 96 selects solutions[1], which is the hash-map alternative. When the user shows the solution cards, the alternative appears selected although the page identifies the brute-force approach as the initial solution. Initialize this state with 0.

Proposed fix
-  const [selectedSolution, setSelectedSolution] = useState(1);
+  const [selectedSolution, setSelectedSolution] = useState(0);

Do not report discovery and scoring before evaluation.

The page starts with two discovered solutions and a 91% score. Submit Alternative only sets alternativeFound to true. Update Score only sets analyzed to true. A user can receive success feedback without submitting a solution or trade-off explanation.

Collect candidate input, evaluate it, and derive the displayed scores from that evaluation. If evaluation is outside this page's scope, label these values and actions as a read-only example instead of candidate results.
