1. Online Assessment – Basic aptitude and computer science MCQs. 2. Technical Interview – Questions on your resume, Java, OOP, DBMS, SQL, projects, plus a few logic puzzles. 3. Case Study Round – You were given a business problem (optimizing Amazon deliveries) and had about 10 minutes to propose a solution. 4. Psychometric Assessment – Behavioral and personality evaluation. 5. Offline Technical Round – Deeper discussion on your projects, technical concepts, and additional puzzles. 6. Stakeholder Round – Focused on your resume, project value, business impact, and finance-oriented discussions. 7. Future Fit/CXO Round – Leadership team assessed your long-term fit, communication, and overall potential.

The initial interview process was in 2 parts: technical and case study. The technical part contained a few questions based on my resume and a few behavioral questions (may vary depending on the interviewer), and if you pass that, you head on to the case study part. The case study part can be solved if you use your common sense and creativity. Overall, it was a decent process.

ION has a long process which has multiple number of rounds. The first round is the technical interview, then another technical which is offline, then a manager round, and then a culture fit round.
