Interview Process

The interview consisted of 4 rounds:

  1. Technical Screening - The interviewer asked about data structures, algorithms, and basic iOS concepts.
  2. System Design - I was asked to design a simple feature for the app.
  3. Behavioral Interview - This round focused on my previous work and how I handle team dynamics.
  4. Coding Challenge - I worked on a LeetCode-style problem involving strings and arrays.

Overall, the interviewers were friendly and the environment was welcoming. I felt comfortable asking questions throughout the process. I received feedback within a week which was positive, but the final decision took longer than expected.

Technical Questions

  1. Two Sum (Array, Hash Table)
  2. Binary Tree Maximum Path Sum (Tree, Depth-First Search)
  3. Reverse Linked List (Linked List)

Tips & Insights

Be prepared to discuss both technical and behavioral aspects of your experience. Familiarize yourself with common data structures and algorithms, and practice coding problems similar to those found on LeetCode.
