1. Initial call with recruiter
2. Codility challenge (2 hours of LeetCode medium and SQL)
3. Final onsite (4 rounds):
   • Design
   • Database
   • Data Structures and Algorithms
   • HR round

All rounds were video-based, with no phone screening.

Basic questions about SQL, including joins, primary keys, GROUP BY, HAVING, etc.

LeetCode easy to medium problems: sorting implementation, simple array problems, string manipulation – nothing too difficult.

Lots of OOP basic concepts (4 pillars, method overriding, etc.).

High-level design – not much into detail, but make sure you know what classes to inherit and how to use method overriding.
