  • Practical Task: A mini‑project to build a simple Flask API that reads a CSV file, filters data based on query parameters, and returns JSON.

• The platform automatically evaluates code for correctness, time‑complexity, and adherence to PEP 8 style guidelines.

• Candidates receive a scorecard indicating pass/fail thresholds (≥70 % overall, ≥80 % in the practical task).

• Technical Phone Interview (30‑45 min)

• Conducted by a senior Python developer from the Karnataka delivery center.

• Focus areas:

  • Deep dive into the candidate’s recent projects – architecture decisions, library choices, and performance optimizations.
  • Discussion of Python’s memory management, GIL implications, and async programming (asyncio).
  • Scenario‑based questions: “How would you refactor a monolithic script into a modular package?” or “Explain the trade‑offs between using a relational DB vs. a NoSQL store for a logging service.”

• The interviewer may share a shared‑screen coding exercise (e.g., writing a decorator to log execution time).

• On‑Site Technical Round (Two Sessions, 2 hours total)

• Session 1 – Pair Programming

  • Candidate works alongside a Persistent engineer on a live codebase (a microservice written in Flask).
  • Tasks include adding a new endpoint, writing unit tests with pytest, and committing changes following the team’s Git flow (feature branch → pull request → code review).
  • Evaluators assess problem‑solving approach, code readability, test coverage, and collaboration communication.

• Session 2 – System Design Discussion

  • 45‑minute whiteboard session covering design of a scalable data ingestion pipeline using Python, Kafka, and AWS Lambda.
  • Candidate must outline component interactions, data flow, error handling, and monitoring strategy (CloudWatch, Prometheus).
  • Emphasis on scalability, fault tolerance, and cost‑effective architecture choices.

• Behavioral Interview (45 min)

• Conducted by the hiring manager and an HR business partner.

• Questions target Persistent’s core values: Customer Obsession, Innovation, Ownership, and Teamwork.
