Deutschebank·Software Engineer·Online Assessment (OA)

Jul 2026
Deutsche Bank software engineer interview with two back-to-back coding problems, pretty standard algorithmic stuff. They also wanted test cases written out for each solution, which I wasn't fully expecting.
  • Given the roots of two binary trees, write a function that returns true if the trees are structurally identical and all corresponding node values match.
  • Write a function to check whether a string of brackets is valid, meaning every opening bracket is closed by the correct type in the correct order.

“Recursive solution felt natural here.”

Deutschebank·Software Engineer·Onsite - Behavioral / Leadership

Jun 2026
Deutsche Bank software engineer interview with a behavioral round that was way more technical than the name suggested. They asked about everything from API design to AI tooling to debugging strategy, so don't walk in expecting soft questions just because it says behavioral.
  • What new skill have you picked up recently, and what drove you to learn it?
  • Tell me about a conflict you had with a teammate. What happened and how did it resolve?
  • How did your frontend and backend communicate in a past project? Walk me through the API design, contracts, and how you handled versioning and testing.
  • How was work divided across your team, and what did day-to-day collaboration actually look like?
  • Walk me through how you debug an issue when you're not sure if it's a client problem, server problem, data problem, or environment problem.
  • Do you use AI tools while you work? What for, and how do you avoid introducing risk?
  • How do you use documentation in your day-to-day work, and what's your process for finding answers quickly?
  • Did your project have tests? What kinds, and what was the overall testing strategy?
  • Did you document your project? What did you document and how did you keep it from going stale?
  • If you switched roles or fields at some point, why did you make that move and what did you do to fill the gaps?

“I talked about picking up a new observability tool because our team kept flying blind during incidents.”
