Interview at Neo.Tax

  1. Open with one real engagement that matches Senior Full-Stack Software Engineer. Name US R&D tax credit (Section 41), who you interviewed, and one thing you excluded from the claim. Scope the story to Senior Engineer work, not a generic busy season.

  3. If you lack Expertise in full-stack web development on modern JavaScript/TypeScript stacks, say so and show the closest proof. Do not rename a different credential.
  4. Confirm San Francisco Bay Area (hybrid) and hybrid out loud. Do not promise remote if the posting says hybrid or on site.
  5. Close on how you review someone else's draft. Delivery quality is the job at Neo.Tax.
