Suggestion: The frontmatter references ./images/post-image.png, but there is no images/post-image.png file in this post directory. This will produce a broken cover image (and may fail static asset checks during build). Add the image at that path or update image to a valid existing asset path. [logic error]

Severity Level: Major ⚠️
- ⚠️ Draft blog post metadata references non-existent image file.
- ⚠️ Future publication risks broken blog listing hero image.
Steps of Reproduction ✅
1. Note the new draft blog file added in this PR at
`content/blog-post-2026-06-21/interview-questions-in-2026-a-practical-guide.mdx` where the
frontmatter on line 7 sets `image: './images/post-image.png'` (confirmed via `Read`
output).

2. Inspect the filesystem under this post directory with `LS
/workspace/frontend-junction/content/blog-post-2026-06-21` and observe there is only the
`.mdx` file and no `images/` subdirectory, so `./images/post-image.png` cannot resolve
relative to this file.

3. Search the entire repo for `post-image.png` using `Grep` and `Glob` (no matches in
`/workspace/frontend-junction`, including `content/blog/images` and `public`), confirming
that `post-image.png` does not exist anywhere in the codebase.

4. Compare with existing published posts in `content/blog` that use `image: ./images/...`
(e.g., `content/blog/frontend-system-design-patterns-2026.mdx` line 5) and have
corresponding files under `content/blog/images/` (verified via `LS`), and see how the blog
listing (`app/blog/page.tsx:63-77` passes `image={post.image}` to `PostItem`) and detail
page (`app/blog/[...slug]/page.tsx:93-103` renders `<Image src={post.image.src} />`) rely
on these image assets; when this new draft post is eventually moved into the
`content/blog` tree and processed by the Velite `posts` collection
(`velite.config.ts:11-23` with `image: s.image().optional()`), the non-existent
`./images/post-image.png` will either fail asset resolution at build time or render as a
broken cover image in these pages.

Validate the correctness of the flagged issue. If correct, How can I resolve this? If you propose a fix, implement it and please make it concise.
Once fix is implemented, also check other comments on the same PR, and ask user if the user wants to fix the rest of the comments as well. if said yes, then fetch all the comments validate the correctness and implement a minimal fix

Add the missing hero image file to the blog post directory.

The frontmatter references ./images/post-image.png on line 7, but this image file does not exist. Create the images/ subdirectory in content/blog-post-2026-06-21/ and add the post-image.png file to prevent a broken image on the published post.

# Interview questions in 2026: A Practical Guide

Interview questions continues to evolve in 2026, and staying current with the latest patterns and best practices is essential for building modern, performant web applications. In this guide, we'll explore practical techniques you can implement today.

## Why Interview questions Matters

Understanding interview questions is crucial for frontend developers who want to build responsive, accessible, and maintainable applications. Whether you're working on a small project or a large-scale enterprise application, these concepts apply.

## Key Concepts

### 1. Foundation Principles

The core principles behind interview questions remain consistent, but implementation details have evolved. Here's what you need to know:

```typescript
// Example of modern interview questions pattern
function useModernPattern() {
// Implementation example
return {
apply: () => {
console.log("Applying modern interview questions pattern");
}
};
}
```

### 2. Common Pitfalls to Avoid

- **Ignoring performance**: Always measure before optimizing
- **Over-engineering**: Start simple, add complexity when needed
- **Not following conventions**: Stick to established patterns in your codebase

### 3. Best Practices

1. Start with the basics before moving to advanced patterns
2. Test your implementations thoroughly
3. Document your code for future reference
4. Keep performance in mind throughout development

## Real-World Example

Here's a practical example you can adapt for your projects:

```typescript
// Real-world application example
interface Props {
data: string[];
onUpdate: (value: string) => void;
}

function Component({ data, onUpdate }: Props) {
return (
<div>
{data.map(item => (
<button key={item} onClick={() => onUpdate(item)}>
{item}
</button>
))}
</div>
);
}
```

## Conclusion

Interview questions is an essential skill for modern frontend developers. By understanding these patterns and implementing them in your projects, you'll build better applications that are more maintainable and performant.

Start with the basics, practice regularly, and gradually incorporate more advanced techniques into your workflow. The key is consistency and continuous learning.
