A platform that delivers measurable improvement in technical interview performance through targeted practice that mimics real interview conditions.

The pain

Job seekers spend weeks on LeetCode grinding random problems, then freeze during actual interviews because they never practiced under time pressure, with real feedback, or against the specific question patterns their target company asks. They waste time on problems that don't match what they'll actually face.

The gap

Existing tools are either too generic (LeetCode, HackerRank) or too narrow (company-specific prep). Nothing connects practice directly to measurable interview outcomes. No tool shows you the exact types of problems Google asks versus Amazon, or gives you realistic mock interviews with actual timing and scoring.

Build angle

Start by collecting interview data from actual candidates, what questions they got asked, how they performed, what preparation actually moved the needle. Build a tool that shows candidates the exact problem distribution for their target company, then delivers timed mock interviews with scoring that predicts real performance. Charge based on company-specific prep packs or monthly access.

Strengths

  • Clear, painful problem with measurable outcomes (pass/fail interviews)
  • Candidates actively spend money on prep, existing market with proven willingness to pay
  • Data advantage possible: collect real interview questions and outcomes to build predictive models
  • Multiple revenue angles: B2C subscriptions, B2B licensing to bootcamps, recruiting partnerships

Risks

  • LeetCode and similar platforms are entrenched with massive free user bases; competing on breadth is unwinnable
  • Interview question data is proprietary and hard to collect at scale without insider access
  • Outcome measurement is difficult, you won't know if someone got the job for months, making feedback loops slow
  • Market is crowded with specialized prep tools (AlgoExpert, Educative, Pramp); differentiation must be sharp or you're another me-too player
  • Candidates may use your tool but still fail interviews due to factors outside your control (communication, system design thinking, luck)
