How Apna Scaled AI Job Matching for 50 Million Users – And How You Can Too

March 20, 2025

AI in recruitment is transforming the hiring process by automating tasks like resume screening, candidate matching, and interview scheduling. It helps businesses save time, reduce bias, and improve the overall candidate experience while finding top talent efficiently.

Finding the right job can be challenging, especially for blue-collar workers who face limited access to digital job portals, language barriers, and skill mismatches. Apna, India’s leading job-matching platform, recognized this struggle and leveraged AI-driven recruitment solutions to connect millions of job seekers with employers efficiently.
Apna’s success in scaling to 50 million users offers valuable insights into building a robust, AI job matching platform. How did they do it? And more importantly, how can you apply these strategies to improve job matching in your own organization? Read on to find out.

The Challenge of Scaling Job Matching for Millions

AI-based job matching is not an entirely known concept, especially in fast-growing countries like India, but it is definitely growing in popularity. What is not simple, is the fact that scaling a platform to equitably and adequately serve millions of users with jobs, is not a walk in the park. Challenges such as user heterogeneity, data dissimilarity, or bias consideration must be addressed which can only be solved with great technological creativity and specific market solutions tailored to that region. Apna is a prime illustration of how these obstacles can be overcome.

Understanding Apna’s User Base

Taking a deeper look at Apna’s target audience, we see that they mainly focus on the blue-collar segment in India, which remains untouched as far as job opportunities are concerned. Reportedly, they have users from the delivery executive, electrician, sales executive, and a multitude of other professionals who do not have conventional ways of searching for jobs.
So, why is this audience significant, you might ask? They are the fundamental building blocks of the ever-growing Indian economy and still remain unnoticed by platforms that majorly deal with white-collar jobs. Apna bridges this gap with an AI in talent acquisition strategy tailored to their needs:

• Multilingual support: With over 11 Indian languages integrated into the platform, Apna ensures that language is never a barrier.
• Simplified access: Job seekers can connect with employers and recruiters in just a few steps, even if they’re new to using mobile apps.
• Community features: Workers can join interest-based groups to ask questions, seek advice, and grow their skills.

How Apna Built a Scalable AI Infrastructure

Real-time data processing and robust infrastructure were essential to scale AI in recruitment for millions of users. Apna built its platform with:

The Role of Data Lakehouse Technology

To unify data for storage and processing, Apna adopted an AI-powered data lakehouse. Data lakehouse architecture merges data lakes and warehousing to lower costs while simultaneously increasing performance. For Apna, this model provided a single source of truth that their AI models could rely on.

• Improved Data Storage: The Apna organization can streamline structured, semi-structured, and unstructured data sets in a single place because of the Medallion architecture integrated into the lakehouse.
• Real-Time Access: Using Apache Hudi, Apna can now access and analyze multi-terabyte datasets in real-time as the core of the system.
• Machine Learning Use Cases: Apna engineers can test, train, and deploy as many as seven AI models every day with the lakehouse, which allows constant innovation.

Workflow Optimization Using Google Cloud

To support its machine learning operations, Apna deployed its infrastructure on Google Cloud and utilized Kubernetes Engine, BigQuery, and Vertex AI.

• Kubernetes Engine: Enables microservices management and deployment for applications.
• BigQuery: An analytics service that stores and queries massive amounts of data making it useful in decision-making processes.
• Vertex AI: Allows unsupervised model retraining and can run several AI refinement processes daily.

Key AI Strategies for Job Matching at Scale

It is not straightforward to expand AI-powered job matching to millions of users. The story of Apna teaches us how to do it right.
