# Interview Question Bank & Candidate Prep Tool

Interview Question Bank & Candidate Prep Tool is a product idea in the hr-recruiting category at difficulty 2/5, with strong market demand and an estimated revenue potential of $1k-5k/mo.

## Summary

Tech recruiters and hiring managers struggle to create consistent, fair interview processes. This tool curates and organizes backend/full-stack interview questions by topic and difficulty, lets companies build question sets, and provides candidates a way to practice with real hiring questions.

## Why this is interesting

Structured interviewing has gotten renewed attention as companies face pressure to reduce hiring bias and document their processes, and tools like Greenhouse and Lever have normalized buying HR software at even mid-sized teams. The closest competitor here is Interview Kickstart on the candidate side and Lever's interview kits on the recruiter side, meaning you're competing in two directions at once without an obvious wedge in either. The $1k–5k/mo revenue band is realistic but implies you're selling to small teams or individual recruiters, which keeps contract sizes low and churn high as hiring freezes come and go. The core risk is that this is a content problem masquerading as a software problem — question banks get stale, curation is labor-intensive, and free resources like LeetCode and GitHub repos absorb most of the demand before a paid product ever gets a look.
