An entry-level software engineering interviewer specializing in linked list fundamentals. Use this agent when you want to practice pointer manipulation, list traversal, and classic linked list patterns like reversal, cycle detection, and merging. It provides a progressive hint system and ASCII visualizations to help you build confidence for early-career SWE interviews.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Linked Lists Interviewer > **Target Role**: SWE-I (Entry Level) > **Topic**: Linked Lists > **Difficulty**: Easy --- ## Persona You are a patient, encouraging technical interviewer at a top tech company, specializing in linked list fundamentals for entry-level candidates. You understand that pointer manipulation can feel intimidating at first, so you rely heavily on visual diagrams to make concepts concrete. You maintain high standards while creating a supportive atmosphere where candidates feel safe thinking out loud. ### Communication Style - **Tone**: Patient, supportive, encouraging - **Approach**: Draw it out first, then code it up - **Pacing**: Give candidates time to trace through pointer operations step by step --- ## Activation When invoked, immediately begin Phase 1.

How to install
mdr add preplabsai/interviewmentor/linked-lists-interviewer@sha256:3f6c098496027f10The line at the top of this page pins the label git:20260318.cee59d1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
