Broadcom SDE interview questions coding and system design 2026

What is the average salary for a Software Development Engineer at Broadcom?

The average salary for a Software Development Engineer at Broadcom is $175,000 per year, with a sign-on bonus ranging from $25,000 to $75,000.

In a recent debrief, the hiring manager at Broadcom emphasized the importance of system design skills, stating that "a strong SDE candidate should be able to design a scalable system with a latency of less than 10 milliseconds." This requires a deep understanding of computer science fundamentals, including data structures, algorithms, and software design patterns.

For instance, a candidate may be asked to design a caching system that can handle 10,000 requests per second, with a cache hit ratio of at least 90%. To answer this question, the candidate should provide a detailed design, including the choice of data structures, the caching algorithm, and the system's scalability and performance characteristics.

How many rounds of interviews can I expect for a Broadcom SDE position?

The typical interview process for a Broadcom SDE position consists of 5-7 rounds, spanning over 20-30 days, with a mix of coding, system design, and behavioral interviews.

One of the most critical rounds is the system design interview, where candidates are asked to design a complex system, such as a chat application or a recommendation engine. For example, in a recent interview, a candidate was asked to design a system that can handle 100,000 concurrent users, with a latency of less than 50 milliseconds.

The candidate's response should include a detailed design, including the system's architecture, the choice of technologies, and the scalability and performance characteristics. A good answer might include a discussion of the trade-offs between different design choices, such as the use of a relational database versus a NoSQL database.

What are the most common coding interview questions asked at Broadcom?

The most common coding interview questions at Broadcom include problems related to data structures, such as arrays, linked lists, and trees, as well as algorithms, such as sorting, searching, and graph traversal, with a focus on solving problems within a time complexity of O(n log n) or better.

For instance, a candidate may be asked to write a function that can sort an array of 10,000 integers in less than 1 second, or to implement a data structure that can store and retrieve 100,000 key-value pairs in less than 10 milliseconds.

To answer these questions, the candidate should provide a clear and concise implementation, including a discussion of the time and space complexity of the solution. A good answer might include a comparison of different algorithms or data structures, such as the use of a hash table versus a binary search tree.

Can I expect any system design interview questions at Broadcom?

Yes, system design interview questions are a crucial part of the Broadcom SDE interview process, with a focus on designing scalable, efficient, and reliable systems, such as a cloud-based storage system or a real-time analytics platform.

In a recent interview, a candidate was asked to design a system that can handle 10,000 requests per second, with a latency of less than 50 milliseconds. The candidate's response should include a detailed design, including the system's architecture, the choice of technologies, and the scalability and performance characteristics. A good answer might include a discussion of the trade-offs between different design choices, such as the use of a load balancer versus a distributed database.
