Interview prep has quietly split into specialties. The playbook for a coding role looks nothing like the one for AI engineering, which looks nothing like the one for a Forward Deployed Engineer. Below are six of the best free, open-source repos, one per track, each maintained by people who've sat on both sides of the table. Pick the one that matches the job you're chasing.

1. DevOps & SRE

Real interview experiences collected from 85+ companies (Amazon, Oracle, JPMorgan, TCS, Infosys, and many more), organized company by company. Instead of a generic question bank, you get the actual questions candidates were asked across Kubernetes, Terraform, AWS/Azure/GCP, CI/CD, Linux, and SRE fundamentals. Search for a target company or browse broadly to gauge what real rounds look like.

2. AI Engineering

Data-driven prep built from 2,445 real job descriptions. Covers the full interview process (theory, coding, project deep-dives, system design, behavioral, take-homes) with company-by-company breakdowns and tailored learning paths for people transitioning in from backend, data, or ML roles.

3. MLOps & ML Engineering

Written by someone who used these exact notes to land offers from Meta, Google, Amazon, Apple, and Roku. Organized around the real interview modules: coding, ML coding, ML fundamentals, ML system design, agentic AI, and behavioral.

4. AI System Design

A "living book" for production AI systems, kept current as new models ship. Pairs a 122-question interview bank with answer frameworks, whiteboard exercises, and ~15 worked case studies covering RAG, agents, MCP, and cost/latency tradeoffs. Ideal for senior and staff design rounds.

5. Forward Deployed Engineer (FDE)

The definitive roadmap for the FDE role (think the "Delta" role at Palantir, OpenAI, and Scale AI). A three-phase curriculum (data engineering, then cloud/GCP, then consulting) plus an applied AI playbook and an interview blackbook with case studies, high-frequency questions, and copy-paste artifact templates.

6. Coding & Core Technical

The heavyweight, from the author of Blind 75. A condensed prep kit so you don't grind LeetCode blindly: the Grind 75 plan, algorithm cheatsheets, a FAANG-ready resume guide, and behavioral questions. If you're not sure where to start, start here.

All six are free and actively maintained. Star the ones you'll use so they're easy to find later. 🚀
