AI LeetCode Interview Assistant

AI for LeetCode Interviews

LeetCode-style interviews are the standard for software engineering roles. Companies use platforms like HackerRank, CodeSignal, and Codility to test algorithmic problem-solving. GhOst provides real-time assistance through a native desktop workflow with managed AI and dedicated privacy controls.

Supported LeetCode Patterns

• Arrays & Strings
• Two Pointers & Sliding Window
• Binary Search
• BFS & DFS
• Dynamic Programming
• Trees & Graphs
• Backtracking
• Heap & Priority Queue
• Union Find
• Topological Sort

What should you practice for LeetCode-style interviews?

Use GhOst as a managed-AI preparation partner for recognizing problem patterns, deriving a solution from constraints, testing edge cases, and explaining time and space complexity. Start from your own notes, code, project history, or a fictional practice prompt. Ask for questions, counterexamples, and critique rather than a polished answer you cannot defend. The useful outcome is a repeatable reasoning process that still works when the interviewer changes the prompt.

A repeatable mock-interview workflow

1. Define the target: record the role, seniority, likely format, time limit, and the evidence or skill the round is designed to assess.
2. Attempt before reviewing: answer once without assistance so the baseline reflects your current reasoning, not an AI-generated response.
3. Request focused feedback: ask GhOst to identify one missing assumption, one weak explanation, one edge case, and one follow-up question.
4. Revise in your own words: produce a shorter second attempt and explain why each material change improves the answer.
5. Repeat under time: return on a later day with a related prompt so you test transfer rather than memorization.

Worked practice exercise

Take one unseen medium problem. Spend five minutes clarifying inputs and constraints, propose a brute-force baseline, identify the limiting cost, then derive and test an improved approach.

Complete the exercise in three passes: a direct answer, the reasoning or evidence behind it, and a short summary of limitations or next checks. If GhOst suggests a fact, formula, API, or policy, verify it before treating it as correct.

How to review the result

Score the answer from one to five for correct interpretation, progressive reasoning, valid invariants, edge-case coverage, complexity analysis, and readable code. Keep the review concrete: quote the sentence, calculation, design choice, or code path that supports each score. A lower score is useful when it identifies the next drill.

Responsible use

LeetCode practice can include explanations and feedback. Employer assessments may use different rules, so do not assume that resources allowed during practice are allowed during a timed screen. Preparation, mock interviews, accommodations, take-home or open-book work, and explicitly permitted assistance are the safe default contexts.
