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
Walk me through a time a live trading system went down and you were the one who had to figure out why. What did you actually do in the first five minutes?
What they are checking: whether they have a real triage instinct versus a rehearsed process, and how they behave under actual pressure
Describe the worst production incident you've been part of. What was your role, and what changed afterward because of it?
What they are checking: ownership of outcomes and whether they drive follow-through like retrospectives and fixes, not just firefighting
Tell me about a time you had to explain a technical problem to someone non-technical, like a trader, in the middle of a stressful situation. How did you decide what to say?
What they are checking: ability to translate technical detail into something a trader can act on quickly
What's a runbook or piece of documentation you've written or improved, and how did you decide what belonged in it?
What they are checking: whether they actually build institutional knowledge or just fix things and move on
Tell me about a time you disagreed with a developer or trader about the cause of an issue. How did you resolve it?
What they are checking: collaboration and conflict resolution across technical and non-technical stakeholders
What would you do
Say it's 9:35am, markets are open, and a trader tells you orders aren't going through on one of the exchange connections. What do you check first, and why?
What they are checking: whether their diagnostic order of operations makes sense for a live trading context, not just general IT triage
You're in the middle of resolving an incident and a trader is asking you for updates every two minutes while you're still trying to diagnose the root cause. How do you handle that?
What they are checking: ability to manage stakeholder communication without sacrificing focus on the actual fix
You've resolved an outage but you're still not sure what actually caused it. The trading day is over and everyone wants to move on. What do you do next?
What they are checking: whether they push for root cause and documentation even when the pressure is off
Two systems are both showing errors at the same time and you don't know if they're related or coincidental. How do you figure out which one to chase first?
What they are checking: prioritization logic when facing ambiguous, simultaneous problems
About the work
Tell me about a bash or python script you wrote to automate something manual. What was the process before, and what did it look like after?
What they are checking: real hands-on scripting experience versus theoretical knowledge of the languages
Give me an example of a Linux command line troubleshooting session you'd run if a process is consuming abnormal CPU or memory on a production box. Walk me through it.
What they are checking: actual CLI fluency versus familiarity with the idea of Linux troubleshooting
How would you write a SQL or Snowflake query to pull all failed orders from the last hour, if you had a table of order events with status and timestamp columns?
What they are checking: basic database querying competence for a role that touches order and trade data
If you had to monitor a production trading environment for anomalies without being told exactly what to look for, what signals would you set up alerts on?
What they are checking: proactive thinking about monitoring and whether they understand what matters in a trading system versus generic infrastructure
