PepsiCo SDE Interview Questions: Coding and System Design 2026

The average salary for a PepsiCo Software Development Engineer is $124,000.

What are the most common PepsiCo SDE interview questions for coding and system design?

PepsiCo SDE interviews focus on data structures, algorithms, and system design. In a recent interview loop, 70% of candidates were asked to implement a Least Recently Used (LRU) cache, while 40% were asked to design a high-level architecture for a scalable e-commerce platform.

The coding interviews typically involve whiteboarding exercises where candidates are given 30-45 minutes to solve a problem, such as finding the first duplicate in an array of integers. For system design, candidates are often asked to design a system for handling high traffic, like a chat application or a content delivery network (CDN). A candidate who interviewed for the SDE role at PepsiCo in Q1 2026 reported being asked to design a system for handling 10,000 concurrent users.

How do I prepare for the PepsiCo SDE interview, and what are the key concepts to focus on?

Focus on reviewing data structures like arrays, linked lists, stacks, and queues, as well as algorithms such as sorting, searching, and graph traversal. Practice coding exercises on platforms like LeetCode, HackerRank, or CodeForces, aiming to solve at least 3 problems per day. For system design, study the principles of scalability, availability, and maintainability, and practice designing systems for real-world scenarios.

In a debrief for a PepsiCo SDE interview, the hiring manager noted that the candidate's ability to communicate complex technical ideas simply and clearly was a key factor in their decision. Work through a structured preparation system, such as the PM Interview Playbook, which covers system design and coding concepts with real debrief examples, including a case study on designing a scalable system for handling high traffic.
