Example scenarios:

• Designing a thread-safe connection pool that limits the number of active database connections.
• Identifying and resolving a race condition in a multi-threaded transaction processing system.

Take-Home Assignment & Solution Walkthrough

Ping Identity frequently uses a take-home programming assignment to evaluate your practical coding style. This project is designed to mimic real-world tasks you would encounter on the job, such as building a microservice, implementing a specific concurrent workflow, or setting up a localized cloud infrastructure.

Be ready to go over:

• Code Quality & Readability – Clear naming conventions, logical package structures, and appropriate documentation.
• Test Coverage – Comprehensive unit and integration tests demonstrating that your solution handles edge cases and failures gracefully.
• Design Decisions – During your panel walkthrough, you must be prepared to defend your architectural choices, discuss trade-offs, and explain how you would scale your solution in production.

System Design & Security Domain

In this stage, you will design a complex distributed system from scratch. Interviewers want to see how you approach ambiguity, define system boundaries, and incorporate security protocols into your architectural designs.

Be ready to go over:

• Distributed Systems Fundamentals – Load balancing, caching strategies, database sharding, and message queues.
• API Design & Integration – RESTful API best practices, gRPC, and handling high-volume webhooks.
• Identity & Security Protocols – OAuth 2.0, SAML, OIDC, JWT management, and secure token exchange mechanisms.
