Free Interview Questions API
The Interview Questions API provides categorized, peer-reviewed interview questions ranging from standard behavioral inquiries to complex algorithmic challenges. This API is the perfect backend for interview prep applications, mock interview simulators, and technical screening platforms.
What is a REST API?
An API (Application Programming Interface) allows two software programs to communicate. A REST API uses standard HTTP requests like GET (to read data), POST (to create data), PUT (to update), and DELETE (to remove).
When you send a request to our https://techidea.online/api/v1/interview-questions endpoint, our server responds with a JSON (JavaScript Object Notation) array containing data. You can then display this data in your frontend React, Next.js, or mobile applications.

Code Examples
import { useState } from 'react';
export default function Flashcard() {
const [question, setQuestion] = useState(null);
const getQuestion = async () => {
const res = await fetch('https://api.example.com/v1/interview-questions/random');
const data = await res.json();
setQuestion(data);
};
return (
<div>
<button onClick={getQuestion}>Get Random Question</button>
{question && <h3>{question.text}</h3>}
</div>
);
}Sample Response

"id": "q_1002",
"category": "Algorithms",
"difficulty": "Medium",
"text": "How do you detect a cycle in a linked list?",
"hints": [
"Think about using two pointers.",
"What happens if one pointer moves faster than the other?"
],
"answer_summary": "Use Floyd's Cycle-Finding Algorithm (Tortoise and Hare). Maintain two pointers, slow and fast. If they meet, there is a cycle."
}What to Build (Project Ideas)
Mock Interview Simulator
A web application that simulates a real technical interview environment, prompting users with questions and allowing them to write code or record video answers.
Implementation Steps
- 1. Build a Next.js frontend with an integrated code editor (e.g., Monaco Editor).
- 2. Fetch random technical questions from the API based on the user's selected difficulty and language.
- 3. Implement a timer to add realistic interview pressure.
- 4. Create a grading criteria rubric alongside the API's provided optimal answers.
- 5. Allow users to save their sessions and track improvement over time.
Daily Prep Newsletter Service
An automated service that sends subscribers a daily interview question tailored to their target role.
Implementation Steps
- 1. Set up a Node.js backend with a cron job scheduling system.
- 2. Maintain a database of user preferences (e.g., frontend, backend, data science).
- 3. Query the Interview Questions API daily for a new, unseen question for each user cohort.
- 4. Integrate with an email API like SendGrid to dispatch the daily question.
- 5. Include a link in the email to view the detailed solution on your platform.
Frequently Asked Questions
Are there code snippets included in the answers?
Yes, for technical and algorithmic questions, the API payload often includes an 'example_code' field containing a reference implementation.
Can I filter questions by specific companies?
Absolutely. You can use the 'company' parameter to retrieve questions that have been frequently asked at companies like Google, Meta, or Amazon.
