I applied on LinkedIn, but they called me after almost two months. First, it was a short interview with someone from HR and she scheduled me for the next interview with the development manager. The next interview with the manager was very theoretical. Questions of the type, what is DI, what is the purpose of unit tests, knowledge of development frameworks, etc. A few days after this, they sent me a technical test that I had to solve in a week. Basically I had to develop an API either in DotNetCore, Spring Boot, or NodeJS to simulate a system to rate purchase orders of an online store, and also to give feedback on existing products within an order. Also, I had to use some persistent storage tools and provide proper unit tests. After this, since I finished the project, they scheduled me an interview in which there was a product manager, a senior developer, and the development manager. It is worth mentioning that this interview was rescheduled the same day, after having been waiting for 20 minutes. In the interview that was rescheduled, they asked me why I used the tools I had used and asked me to explain the architecture of the system, from the data layer, the endpoints, and some database diagrams. They also asked to justify the technologies used (in my case Postgres and dot net core). In addition, there were questions about how I could improve performance and also how you would implement some other systems (which I assume they need). In the end, it looked like everything had gone well. I asked for feedback the next week, but they only replied that there were no comments yet. A few days later I contacted them again, but I had no response. In the end, HR contacted me almost 3 weeks later to tell me that the position had already been closed.
