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 had to fix a live production issue under real time pressure with traders waiting on you, what did you do and how did it turn out
What they are checking: composure and decision quality when stakes and stress are both high
Describe a time you disagreed with a trader or developer about whether a change was safe to make, how did you handle it
What they are checking: ability to hold a technical line with non-engineers without damaging the relationship
Tell me about a time something broke in production that was your responsibility, how did you communicate that to the team and what changed afterward
What they are checking: accountability and whether they build durable process improvements after failure
What would you do
Say you need to push a change into the production trading environment during market hours because of a bug, walk me through how you'd assess the risk and decide whether to wait
What they are checking: judgment about change control and operational risk, not just technical fix ability
If monitoring showed a gradual degradation in system health with no obvious single cause, how would you go about isolating the source
What they are checking: systematic incident investigation skills and comfort with ambiguity
This role can require being reachable outside normal hours, tell me about a time you had to respond to something urgent on your own time and how you managed it
What they are checking: realistic expectations and reliability around on-call type availability
How do you decide what needs to be documented versus what can live as tribal knowledge on a fast-moving infrastructure team
What they are checking: judgment about process discipline balanced against speed of a small team
About the work
Walk me through how you would troubleshoot a sudden latency spike on a production trading system, where would you look first and why
What they are checking: whether the candidate has a structured, layered approach to diagnosing performance problems rather than guessing
Explain multicast to me and describe a situation where you'd actually need it in a low latency trading network
What they are checking: real depth of networking knowledge versus surface-level buzzwords
Give me an example of a shell script or Python tool you built to automate some part of managing a production environment, what problem was it solving
What they are checking: practical scripting ability applied to real operational pain points, not academic exercises
How would you go about optimizing network infrastructure for a new low latency application being deployed at a colo site
What they are checking: hands-on understanding of colo design and latency-sensitive network tuning
What Linux commands or techniques do you reach for when a box is behaving strangely and you don't yet know if it's hardware, OS, or application level
What they are checking: depth of hands-on Linux/UNIX troubleshooting versus memorized answers
Explain the difference between routing and switching decisions in a way that connects to why exchange connectivity design matters here
What they are checking: whether foundational networking concepts are actually tied to the trading infrastructure context
