The interview was for a post focusing on back-end with lots of database manipulation. However, the job requirements made it seem like it was full-stack, with a more front-oriented focus. I found this a bit misleading.
The interview with the hiring manager was okay. They would give me examples of functionalities and ask how I would approach implementing them. I liked this part of the interview because it felt very organic, with no wrong or right answers.
The technical interview with the team was, at first, similar in approach to the previous one. They also said, "no wrong or right answers." However, at some point, they started asking more and more specific questions about database querying and security. The interview was very long, so obviously answering the whole battery of questions correctly would have been impossible.
