Optiver Summer 2025 Internships Everything You Need to Know About the Assessment Process, Salary, and Interview Insights {update}

1. Hackerrank Assessment (Part 1)

The first part of the online assessment consists of coding problems hosted on Hackerrank. Based on feedback from previous candidates, this section is known to focus on data structures and algorithms.

Key areas covered in the Hackerrank assessment:

• HashMaps
• Doubly Linked Lists
• Heaps
• Dynamic Programming (occasionally)

The difficulty of these problems can range from easy-medium to medium-hard, with a significant focus on solving the problems optimally.

Tips for Preparation:

• Prioritize practicing data structures and algorithms on platforms like LeetCode or Hackerrank.
• Focus on problems related to HashMaps, linked lists, and heaps.
• Time yourself to ensure you can complete the questions within the allocated time.

2. Coding Knowledge (Part 2)

The second stage of the assessment involves questions that test your general coding knowledge, such as:

• Object-Oriented Programming (OOP) Design
• System Design (often at a high level)

Candidates are typically expected to solve problems that require a solid understanding of OOP concepts like inheritance, polymorphism, encapsulation, and abstraction. These problems may have lengthy descriptions and require deep thinking.

Example Topics:

• Design a simple memory management system.
• Implement classes for a bank account system with varying account types.
• Work with data structures in a way that emphasizes scalability and maintainability.

3. Zap-N (Part 3)

The third part of the assessment is more unique to Optiver and could involve a simulation of real-world trading scenarios or high-stress coding challenges. Feedback from candidates who’ve taken this test suggests it’s designed to evaluate your ability to manage stress and quickly adapt to changes while coding.

Preparation Tips for Zap-N:

• Stay calm and composed while solving problems.
• Practice coding under time constraints to simulate real-world pressure.
• Brush up on topics like multi-threading and concurrency, as these could feature in real-time system tests.
