I’ve been thinking about this a lot recently and wanted to hear other developers’ opinions.

Most big tech companies still focus heavily on **DSA (Data Structures - Algorithms)** in interviews. You’ll often see questions about binary trees, dynamic programming, graphs and other algorithm-heavy topics.

But when I look at my day-to-day frontend work, most of it revolves around things like:

- building UI components

- handling API data

- managing state

- optimizing performance

- fixing layout or browser issues

I rarely find myself implementing things like **graph algorithms or complex tree traversals** in actual frontend projects.

Because of this, many developers argue that spending months grinding LeetCode might not be the most practical preparation for frontend roles.

On the other hand, some people say that **DSA teaches problem-solving skills**, which are useful no matter what kind of development you do.

For example, understanding things like:

- time complexity

- efficient data handling

- memory usage

- algorithmic thinking

can still help when optimizing UI performance or working with large datasets.

Personally, I feel there should be a **balance**.

Knowing the basics like arrays, hashing, recursion, and searching/sorting algorithms makes sense. But expecting frontend candidates to solve extremely complex algorithm questions sometimes feels a bit disconnected from real frontend work.

Maybe interviews should focus more on things like:

- JavaScript fundamentals

- DOM and browser behavior

- performance optimization

- real-world frontend problems

- component architecture

instead of purely algorithm puzzles.

### Curious to hear from others:

• If you're a frontend developer, how much DSA do you actually use?
• Did grinding LeetCode help you in your job?
• Should frontend interviews focus more on **practical frontend problems instead of algorithms?**

Would love to hear different perspectives.
