Was sent OA which had very random questions, most of them were about a broad range of programming languages and concepts which had nothing to do with backend. Questions were about kotlin, ai, java, react. Some questions were incorrectly formatted and used wrong type of editor and one of the questions was there twice.

In generał there was a test which featured various technologies from Java, Swift, SQL to Kotlin and more. It wasn't rally easy but I managed to get to the next stage which was the technical interview. Questions asked there concerned mainly my cv and the answers from the test. They were pretty weird and I don't rally know what was the reason for asking them as I've already answered
