Scalable Capital Senior Java/Kotlin Engineer interview questions

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.

First, there was a 15 minutes call from the company's recruiter. We talked a bit about the company and the reasons that I chose to apply for Scalable Capital. I asked the recruiter if the interview was going to be about a position on the security team (which was mentioned in the job title) and she said that they are not sure. So based on the reviews on Glassdoor, I prepared myself for a more general interview, which I think was the reason why I failed the technical interview because the questions were mostly about security concepts and issues. Then, a Codility test was sent which consisted of two steps. The first one was about a failing test (making corrections to the code until it passes). The second one was implementing a simple CRUD controller. Not all of the tests given passed. But I was invited to the next level. There was some ambiguity considering the naming of the tests and also I gave feedback with a screenshot in which I insisted that one of the test cases was not right. But I received no feedback in return. After that, there was a technical interview with the tech lead. The questions covered a wide range of subjects. From behavioral questions to technical ones. A few days after the interview they replied that I wasn't accepted with a "We will not be proceeding ...." e-mail.
