Likely interview questions for this role
Written from this job description, not a generic list. Each one notes what the interviewer is really checking.
About your past
Tell me about a time you built something in C++ that had to deal with multiple threads running at once. What went wrong, and how did you find it?
What they are checking: whether the candidate has hands-on exposure to concurrency bugs rather than just textbook knowledge
Tell me about a project where you had to talk to someone who wasn't technical to figure out what they actually needed built.
What they are checking: ability to translate requirements from non-engineers, which mirrors working with Quant and Trading
Describe a time you had to learn a new tool or technology quickly to finish a project.
What they are checking: speed of ramp-up, since interns are expected to go from ideation to delivery in ten weeks
Tell me about a time you got fast, unexpected feedback that meant you had to change your approach midstream.
What they are checking: adaptability under pressure, tied to the role's emphasis on reacting quickly to changing conditions
What draws you to a trading firm instead of a more typical tech company, given you don't need finance background for this role?
What they are checking: genuine motivation and fit for a fast-paced, low-latency, high-stakes environment
What would you do
Imagine a trader tells you a system is 'too slow' but can't say exactly what's slow. How would you work with them to pin down the actual problem?
What they are checking: whether the candidate can extract concrete requirements from vague, high-pressure stakeholder feedback
If you were designing a small piece of a distributed system where one component needs to know the state of another over the network, what could go wrong, and how would you plan for it?
What they are checking: awareness of distributed systems failure modes like latency, partial failure, and stale state
About the work
Walk me through what happens in memory when you have a shared resource being read and written by two threads without any locking.
What they are checking: basic understanding of race conditions and why synchronization matters
Say you have a queue that a producer thread writes to and a consumer thread reads from, and you're told to make it as fast as possible with no locks. How would you approach that?
What they are checking: exposure to lock-free data structures and whether the candidate can reason about tradeoffs, not just recite the term
How would you go about finding out why a piece of C++ code that used to run fine is suddenly using ten times as much CPU?
What they are checking: familiarity with profiling tools like perf or vtune and a systematic debugging mindset
You get a segfault that only shows up once every few thousand runs. What's your process for tracking it down?
What they are checking: comfort with tools like GDB, Valgrind, or address sanitizer and patience with intermittent bugs
What's the difference between a mutex, an atomic, and a lock-free approach, and when would you reach for each one?
What they are checking: depth of understanding of concurrency primitives beyond buzzwords
What newer C++ features, from C++20 or C++23, have you actually used, and what problem did they solve for you?
What they are checking: real hands-on modern C++ experience versus only knowing older C++ from school
Here's a coding problem: given a stream of numbers coming in continuously, keep track of the median at any point in time. How would you solve it, and how would you make it fast?
What they are checking: raw algorithmic problem-solving and ability to reason about time complexity under a live setting

About Akuna
Akuna Capital is an innovative trading firm with a strong focus on collaboration, cutting-edge technology, data-driven solutions, and automation. We specialize in providing liquidity on a variety of exchanges across various asset classes, primarily as an options market maker. To do this successfully, we build and maintain our own low-latency technologies, including application frameworks, trading strategies, and mathematical models.
Our Founding Partners first conceptualized Akuna in their hometown of Sydney, Australia. They opened the firm’s first office in 2011 in the heart of the derivatives industry and the options capital of the world – Chicago. Today, Akuna is proud to operate from additional offices around the world: Sydney, Shanghai, Singapore, and London.
What you’ll do as a C++ Software Engineer Intern at Akuna:
C++ software engineer interns at Akuna have the opportunity to work on a variety of high-performance systems that power the firm’s core business operations. Our interns are embedded on small-to-medium-sized teams that frequently interface with Quant and Trading, allowing them to focus on a specific domain area while still experiencing the day-to-day life of an Akuna software engineer. Akuna’s C++ systems are heavily multithreaded, asynchronous, and distributed by nature, which comes with a slew of challenges; our engineers are tasked with ensuring these systems are reliable, efficient, scalable, and flexible enough for even the most niche use cases.
Over their 10-week Akunacademy experience, software engineer interns will work on one or more valuable projects, progressing from ideation and design all the way to delivery and maintenance. These projects range from adding functionality onto existing systems to implementing brand new componentry to experimenting with new technologies and patterns to better understand the solution space. Akuna is looking for software engineer interns who are motivated, can solve complex problems, and are willing to reach for creative solutions when faced with novel problems. We value innovation, hard work, and knowledge, and we want our engineer interns to make a direct impact on the firm. Whether you are interested in algorithms and data structures, concurrency, networking and protocols, performance tuning, data capture and analysis, mathematical modeling, hardware, or something else, there’s engaging work to be done.
