The interview process was structured and multi-round.

It started with an online coding assessment, followed by a live technical interview. The focus was on data structures/algorithms (trees, BST, recursion), system design, and practical problem-solving.

The final round included an applied system design session and a few iOS-specific questions to test depth in mobile development.

The process overall tested problem-solving, scalability thinking, and the ability to explain reasoning clearly.

Given an N-ary tree, print the boundary nodes in anti-clockwise order.

• In a Binary Search Tree, find the value closest to a given double (recursively). • Implement a rate-limiting API algorithm; extend the discussion into iOS-related implementation details. • System design: build a dating app like Tinder, focusing on scalability, user matching, and real-time performance.
