How do you prepare to tech interview? Any tip and tricks?

Hey, I’m working as developer 8 years, and I changed company a couple times, and it was just luck every time, I ruined 90% of tech interviews, but in regular work I can do a lot of things, like invent some solutions, learn new things very quickly, but in interviews I’m absolute loser What can you advise me? How can I better pass job interviews?

A coaching/training platform helping experienced developers overcome interview anxiety and technical assessment gaps

The pain

Experienced developers (8+ years) fail 90% of interviews despite strong real-world capabilities, interview skills don't correlate with job performance, creating frustration and career stagnation

The gap

This is a problem statement, not a business idea. No solution, business model, or differentiation proposed. The founder is asking for advice, not pitching a product

Build angle

Create a specialized interview prep platform for senior developers: mock interviews with experienced engineers, behavioral coaching, pattern recognition for their specific weak areas, or a marketplace connecting them with interview coaches

Strengths

  • Large addressable market (millions of developers globally)
  • Real, validated pain point with emotional resonance
  • Potential for high-value customers (senior devs earn $150k+)
  • Multiple monetization paths (courses, coaching, subscriptions)

Risks

  • Extremely crowded market (LeetCode, AlgoExpert, Interviewing.io, etc.)
  • Unclear why existing solutions don't work for this segment
  • No defensible moat, easy to copy
  • Requires understanding root cause: Is it algorithm knowledge, communication, anxiety, or something else?
  • High customer acquisition cost in competitive space
