For technical recruiters and hiring managers
Hire Developers Who Can Actually Build Systems
Screen and interview developers on their real code—not generic puzzles solved instantly by AI
Our AI reviews their codebase and generates role-specific technical questions.
class CacheManager {
async get(key) {
const cached = await this.redis.get(key);
if (cached) {
return JSON.parse(cached);
}
const data = await this.database.find(key);
await this.redis.setex(key, 3600, JSON.stringify(data));
return data;
}
}How do you handle cache invalidation when the underlying data changes?
Why this question: Tests understanding of distributed systems and common caching pitfalls in production
Coding Interviews are Broken
function twoSum(nums, target) { // LeetCode Problem #1: Two Sum
for (let i = 0; i < nums.length; i++) {
for (let j = i + 1; j < nums.length; j++) {
if (nums[i] + nums[j] === target) {
return [i, j];
}
}
}
}We have the solution
class JobQueue {
async enqueue(jobData: JobPayload) {
return await db.jobs.create({
data: {
payload: jobData,
status: 'pending',
}
});
}
async processNext() {
const job = await db.jobs.findFirst({
where: { status: 'pending' },
orderBy: { createdAt: 'asc' }
});
}
}Why did you implement a database-backed job queue instead of using Redis-based solutions like BullMQ?
Why this question: Reveals architectural decision-making process and understanding of job queue trade-offs
Good signals
Red flags
• How do you handle concurrent workers trying to process the same job?
• What happens when job processing takes longer than expected?
