I applied online. I interviewed at Scalable Capital (Berlin) in Mar 2026
Interview
They send you a codility link. You are supposed to complete it in 7 days. It has 2 coding questions. You're supposed to make the test cases pass. But even after getting 100% score, they still rejected my application. I even reached out to the recruiter to ask for reason but they didn't tell me anything. I think the problem is that they don't review your resume until after you do the test. So the codility test is received by all the applicants whoever applies.
Interview questions [1]
Question 1
Codity questions:
(1) You need to write a @Controller class (TaskController) (using Spring Boot). You need to create simple CRUD methods (get, put, post, delete, getAll). No need to worry about the service class or repository class.
(2) A java class is given which has only 1 method. That method takes string as an input and reverses it and output the result. This method is already given. You just need to write a few test cases for it.

Interview
The interviews were pretty standard.
A simple coding task.
Initial interview with an Engineering Manage who I really enjoyed talking to.
Then a technical interview with seniors having decades of experience as Java developers. However, their knowledge seemed to be limited. I mean which engineering manager, who has worked his whole life as a java developer, would not know how ConcurrentHashMap works?
They asked weird questions and were fixated on me providing exact names and keywords in the answers. I knew then and there that I won't be selected because they were unable to explain the requirements. The task that was written did not match the clarification provided even when I tried to ask questions about it. Ever since the interview started they seemed uninterested, as if they were being forced to sit and interview me. I would never work in a team with such dull colleagues.
It is a pity that a company like Scalable Capital, that has great potential, has hired such people to lead their engineering team.
I am even skeptical of using SC as my investment app after talking to supposed leaders of the tech team with such limited understanding of the programming construct they live upon.
Never again, SC.

I applied online. The process took 1 week. I interviewed at Scalable Capital in Oct 2023
Interview
Without an initial interview I was assigned a Codility test. The tasks were easy, below junior level. However, you're forced to do them using the Codility in-browser "environment", which is hardly better than using Window's Notepad, in Java 8 (a decade old). You're given the DTOs and entities stacked in a sidebar with no kind of syntax highlighting. You're forced to write imports by hand, without any sort of autocomplete or basic error handling. Tests cannot be run individually, so you cannot only test one method and the whole stacktrace of every test is dumped to a console and you have to scroll to infinity to find the relevant information. The task itself is very easy, but using such a tool wastes at least half of the time you're allotted. The tool doesn't even have a "save last working version" functionality to allow you to work to the last second. There is no warning about the time running out, and it will leave you hanging while writing. I had a single small error left after choosing the wrong provided constructor. While fixing it the time ran out just as I needed to close a parentheses leading to a syntax error and the code not being able to compile. All I needed to pass 100% of the tests was two keystrokes. However, the rule is that no matter what, should it occur the interview process is ended. Without trying to fix the error the code would have been 95% and the process would have continued. I explained this situation and was simply written an inflexible generic copy and paste rejection message. My feedback about a lackluster system and unrealistic way of skill assessment went ignored.

Question 1
Write tests for a function that reverses strings and write a Spring controller in Java 8.
Dear evaluator,
Thanks a lot for sharing your valuable feedback on the interview process and especially the Codility challenge. We are sorry if you had problems with the environment. We will definitely consider your feedback and pass it on to the responsible colleagues, as we permanently want to improve our interview process to be able to provide a good candidate experience!
We wish you all the best,
Isabella
