Frequently Asked Questions
How are coding interview problems selected and categorized?
Every problem on Coding Prep Guide is curated from real technical interview loops at FAANG, Big Tech, and top startups. Rather than cataloging thousands of duplicate questions, we map problems directly to core underlying patterns (such as Sliding Window, Two Pointers, Dynamic Programming, and Topological Sort) to maximize conceptual leverage.
Can I submit a correction or alternative optimal solution?
Yes! We maintain strict editorial standards and actively welcome peer review from engineers. When submitting an algorithmic correction, please provide your tested solution code, asymptotic time and space complexity derivations, and any failing edge case inputs.
How frequently is the interview question database updated?
Our team monitors company hiring cycles, online assessments (OAs), and verified interview reports on a weekly basis. We refresh problem frequency scores, company tags, and system design case studies every month to reflect current 2026 hiring trends.
Are you open to tech sponsorships and engineering collaborations?
We selectively partner with developer-focused platforms, educational institutions, and developer tools that provide genuine value to software engineers. Email us directly with "Partnership Inquiry" in the subject line.
Response time: We prioritize reader and community inquiries and respond within 24–48 hours. For algorithmic bug reports or solution corrections, please include the problem URL, programming language, and observed runtime behavior.
