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 build something from scratch instead of pulling in an existing library. Why did you decide to do that, and how did it go?
whether the candidate genuinely enjoys building fundamentals versus just assembling tools, which the posting explicitly values
Describe a project where you had to learn a new tool or language quickly to hit a deadline. What was hard about it and how did you get up to speed?
learning speed and self-direction in a fast-moving, ten-week internship setting
Tell me about a time you disagreed with a teammate about how to build something. How did you resolve it?
ability to collaborate and compromise in a small, fast-paced team
What draws you to working on trading infrastructure specifically, given you don't need any finance background for this role?
genuine motivation and fit versus applying broadly without real interest
Technical
Walk me through a web project you built where you used TypeScript or Python on the front or back end. What did the architecture look like?
whether the candidate has real hands-on experience building with these languages, not just coursework familiarity
Say you need to display data that's updating many times per second on a web page without freezing the browser. How would you approach that?
understanding of real-time UI performance concerns, which matters for a trading platform front end
Explain the difference between a thread and a process, and tell me about a time you had to think about concurrency in something you built.
grasp of threading models mentioned explicitly in the posting, and whether it's applied knowledge or textbook recall
Pick a data structure you'd use to keep a sorted list of live prices updating constantly, and explain why you'd choose it over alternatives.
ability to reason about algorithmic tradeoffs rather than just naming structures
Have you worked with React? Tell me about a component you built that had to manage state that changed frequently or unpredictably.
depth of React experience versus surface familiarity, since it's called out as a plus
What's your experience developing on Linux versus other operating systems, and has that ever caused a problem you had to work around?
comfort with the Linux environment the team actually works in
Have you used AI coding tools like Claude Code in real projects? Walk me through how you used it and how you decided when to trust or override its output.
whether the candidate can use modern AI tools responsibly rather than blindly, which the posting flags as a plus
Situational
Imagine you're on a team that deploys new code every day. You find a bug in a feature that's already gone out. What do you do first?
judgment under a rapid release cadence and instinct for triage versus panic
If a senior engineer gave you a vague task like 'make this dashboard faster' with no other detail, how would you figure out where to start?
comfort with ambiguity and independent problem framing, common in an internship on production code
This internship requires reliable, predictable availability for the full ten weeks. Is there anything about your schedule I should know about?
logistics fit and honesty about commitment constraints before they become a problem
