Why these two guides?

Strong engineers rarely fail because they cannot code. They fail when they cannot explain complexity clearly or recognise the underlying problem pattern quickly enough.

  • Reason about Big-O confidently instead of memorising formulas.
  • Recognise recurring coding patterns and choose an approach faster.
  • Prepare from an interviewer’s perspective, not by grinding random problems.

What you'll get:

Master Big-O — normally €41
  • Understand what each complexity means and when it matters.
  • Compare common approaches without relying on memorised definitions.
  • Explain performance trade-offs clearly under interview pressure.
Master the Coding Patterns — normally €39
  • Learn eight recurring patterns used across coding interview problems.
  • Follow clear explanations and worked examples.
  • Build a repeatable process for recognising a problem and choosing an approach.

Why €17?

This is a one-time welcome offer for new subscribers. It gives you two focused, practical resources at a lower entry price before you decide whether you need more personalised preparation.
