Study Plan

1

Data Structures and Complexity

Weeks 1-2: Data Structures (Arrays, Lists, Trees, Graphs) & Complexity Analysis.

Weeks 1-2: Focus on core data structures like arrays, linked lists, stacks, queues, hash maps, trees (binary trees, BSTs), and graphs. Practice implementing them and solving problems related to their usage. Understand their time and space complexities.

2

Algorithms

Weeks 3-4: Algorithms (Sorting, Searching, Recursion, DP, Graph Traversal).

Weeks 3-4: Dive into algorithms, including sorting (bubble sort, merge sort, quicksort), searching (binary search), recursion, dynamic programming, and graph traversal algorithms (BFS, DFS). Practice solving problems that require these algorithms.

3

Object-Oriented Programming

Week 5: OOP Concepts & Language Fundamentals.

Week 5: Focus on object-oriented programming concepts (encapsulation, inheritance, polymorphism, abstraction) and design patterns. Review common programming languages used at Niantic (e.g., C++, Java, Python).

4

Behavioral and Company Fit

Week 6: Behavioral Questions (STAR method) & Company Research.

Week 6: Prepare for behavioral questions. Think about specific examples from your past experiences that demonstrate teamwork, problem-solving, leadership, and handling challenges. Practice articulating these using the STAR method. Also, research Niantic's mission, values, and recent projects.

Interview Rounds

3-step process with detailed breakdown for each round

1

Coding Challenge

Coding challenge focusing on data structures and algorithms.

Technical Interview (Data Structures & Algorithms)Medium
45 minSoftware Engineer

This round focuses on assessing your core data structures and algorithms knowledge. You will be asked to solve one or two coding problems on a shared online editor. The interviewer will evaluate your problem-solving approach, coding style, and ability to explain your solution and its complexity.

What Interviewers Look For

A candidate who can translate a problem into working code.Someone who can analyze the complexity of their solution.A candidate who can articulate their thought process clearly.Attention to detail in coding practices.

Evaluation Criteria

Correctness of the solution
Efficiency of the solution (time and space complexity)
Clarity and readability of the code
Ability to communicate the approach and reasoning

Questions Asked

Given a string, find the length of the longest substring without repeating characters.
