Technical interview preparation

Who it is for

Interviewing for backend or full-stack roles

What you can do after

Handle the coding round, the design round, and the "why did you build it that way" round.

4 courses · 136 lessons available · Four courses · the design ones reward being slow

  1. 1

    Data Structures & Algorithms

    11 lessons

    The coding round. Patterns rather than puzzles - two pointers, sliding window, and knowing which one a question is really asking for.

  2. 2

    Design Patterns

    23 lessons

    The vocabulary interviewers use without defining. Knowing what a factory or an observer is stops you decoding the question instead of answering it.

  3. 3

    Architecture Patterns

    56 lessons

    The design round. How whole systems are shaped, and what each choice costs - which is the part candidates skip.

  4. 4

    Microservices Patterns

    46 lessons

    The follow-up questions. Resilience, data, and communication between services, where senior interviews spend most of their time.
