System Design Roadmap in 2024

Throughout the last two years, there have been several changes to technical interviews. The most frequent and notable change is the system design interview. Having a single system design interview has become mandatory. Understanding design, thought processes, and the capacity to create any product from start, regardless of experience level—from one year to over ten—are the goals of this interview.

Here is a more detailed roadmap that you can use in 2024.

Note: I'll be writing in-depth posts on each topic shortly.
