Likely interview questions for this role
Written from this job description, not a generic list. Each one notes what the interviewer is really checking.
Behavioral
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
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
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
accountability and whether they build durable process improvements after failure
Technical
Walk me through how you would troubleshoot a sudden latency spike on a production trading system, where would you look first and why
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
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
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
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
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
whether foundational networking concepts are actually tied to the trading infrastructure context
Situational
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
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
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
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
judgment about process discipline balanced against speed of a small team
