I applied through a recruiter. I interviewed at N26 (Berlin) in Jan 2019
Interview
Unprofessional attitude towards interview.
I was asked about software unit-testing, told them about TDD, basic java libraries and techniques.
Their answer was sorry, but you were too talkative, not up to point.
I write java tests as long as 5 years and they just declined my unit-testing basic answers. Stupid interview
Thanks for sharing your feedback with us. Over the past months we have made it a priority to give all rejected candidates constructive feedback. You can go back to your recruiter and ask them to provide you with further explanation to better understand the reasons.
Other Senior Software Engineer interview reviews for N26
I was being recruit for Senior Software Engineer Role.
Over all process consist of
Recruiter Chat
Online Leetcode Task submission
Live coding round
Technical discussion + System design round
Cultural fit round
I went upto the System design round
Interview questions [2]
Question 1
For the Live coding,
there was a pre written code and tests,
You have to read the requirements,
Understand if code if fulfilling the requirements. Run the test case, fix if any is failing,
Figure out the missing tests and correct the wrong code.
Scenario of the code was
A Service provides functionality to monitor stock prices and alerts the user
when the price is equal to or lower than a specified target price.
System Design round:
Half of the time were related to technical discussions, your projects how you led them processes etc.
2nd half was a system design round.
Scenario was design the Signup process for a live bank

I applied online. The process took 1 day. I interviewed at N26 in Apr 2025
Interview
a call with HR for a whole 45 minutes. Everything was ok until she asked the question "Where do you see yourself in 5 years?" Seriously?! Are you still asking this? Normal HR stopped asking this question 10 years ago, but apparently N26 conducts interviews using 15-year-old scripts. It is impossible to answer this question with the truth, it provokes lies. They probably expected me to answer that I see myself as at least a director and am ready to weave intrigues, manipulate, and put everything on the altar of this goal. The question shows ignorance of the specifics of IT - a company asking such questions demonstrates a lack of understanding of modern technical culture. By the way, in the story about N26 there was nothing about their career ladders.
I applied online. The process took 4 weeks. I interviewed at N26 (Barcelona) in Mar 2025
Interview
The interview process at N26 consists of four stages:
An online coding assignment on Codility
A coding challenge with two N26 engineers, focused on algorithmic problems
A systems design round
A behavioral round
Feedback usually takes 2–3 days after each stage, but the scheduling is quite disorganized. Instead of letting candidates provide availability, they force you to choose from a limited set of time slots, which can be a week or more out - unlike other companies that schedule interviews ASAP.
The Interview Experience
The technical questions were surprisingly easy compared to other companies in the same space.
Codility: One basic debugging problem and two medium Leetcode-style algorithm problems.
Second coding round: Another straightforward Leetcode problem.
Systems design: A simple FinOps-related design problem.
Behavioral: Standard questions on conflict resolution, mentoring, and working under deadlines.
The Major Issues
The entire process felt unorganized and incohesive from start to finish.
JVM Bias: Despite making it clear multiple times that I don’t work with Java/Kotlin, I was forced to use Java in Codility. Then, in the next round, the interviewers (who were clearly unprepared) gave me another Java problem - this time in a broken coding environment. I solved it anyway (including test coverage), and since they had nothing left to ask, we just wasted the rest of the interview talking.
Disjointed Behavioral Round: It was a complete mess. They seem to be mimicking American-style behavioral interviews without actually understanding their purpose. They expect answers to match their internal experience at N26 - deviate even slightly, and they start shaking their heads and taking notes. For example, they asked about my Agile experience, and when my responses didn’t align with their specific Agile implementation, they seemed to take issue with it. Similarly, when I mentioned managing "2 front-end and 1 back-end" developers, they bizarrely concluded that I lacked experience managing backend engineers.
The Rejection & Absurd Feedback
I was ultimately rejected with feedback that made no sense:
“Not from the JVM world” - despite HR explicitly assuring me this wouldn’t be a problem.
“Not enough mentoring experience with BEs” - despite having mentored entire teams, SDETs, and interns at past companies. They framed their questions in a way that set up misleading conclusions instead of actually exploring my experience.
Final Thoughts
Given the chaotic interview process, questionable evaluation criteria, and an underwhelming compensation package, N26 simply isn’t worth the effort.

Question 1
A Codility test with one easy and 2 medium Leetcode-style problems (both on Leetcode).
