BugFree.ai

What is BugFree.ai?
BugFree.ai is an interview prep platform built around interactive practice for system design, data, and behavioral rounds. It positions itself as a LeetCode-style experience for non-coding interview formats, with guided walkthroughs, scored feedback, and curated question banks you work through step by step.
The platform splits prep into distinct tracks: system design (including object-oriented and machine learning design), data interviews covering metrics, SQL, A/B testing, and case studies, plus behavioral questions with STARL-style answer frameworks. Learning paths are organized by experience level, from junior to specialist, with topics like distributed architecture, messaging systems, and collaborative tools.
Mock interview modes simulate real sessions across system design, OOD, ML, behavioral, data, and LeetCode-style coding questions. A separate interview experiences library lets you browse reports from candidates at companies like Google, Meta, Amazon, and Stripe, filterable by role and company.
It is aimed at software engineers, data scientists, and machine learning engineers preparing for technical interviews at top tech companies.
