naildd is an interview-prep platform built for the full spectrum of tech roles — software engineers, product managers, designers, and data & analytics professionals. One product, many interview tracks: each role gets its own question bank, skill radar, and worked solutions.

We index 1,500+ real interview questions from FAANG and top tech companies, focused on the reasoning interviewers actually want to hear — not just syntax.

What this blog covers

  • Question walkthroughs — real interview questions broken down step by step
  • Company guides — what to expect at Google, Meta, Amazon, and 30+ other tech companies
  • Skill deep-dives — SQL window functions, system design patterns, A/B testing pitfalls, product sense frameworks
  • Career posts — switching roles, salary negotiation, ramping at a new company

Why we exist

Most interview prep is fragmented: scattered Glassdoor questions, Stack Overflow threads, paid courses that teach syntax instead of judgement. naildd consolidates the highest-signal questions from real interview loops and explains why — the reasoning interviewers want to hear.
