Data Structures & Algorithms Basics
Part of the Data Science Roadmap
In short
Lighter-weight than a pure software engineering interview, but basic comfort with arrays, hashmaps, and time complexity is often still expected, especially at larger tech companies.
How to learn this
- 1Review basic data structures (arrays, hashmaps, sets) and their typical time complexities.
- 2Practice a handful of easy-to-medium coding problems on a standard practice platform.
- 3Learn to state a solution's time complexity out loud as part of your answer.
