J'ai postulé via un recruteur. J'ai passé un entretien chez Trendyol (İstanbul) en oct. 2025
Entretien
The process starts with an application, followed by a Codility test, an HR phone screening, and an online interview with HR and the hiring manager. Then comes a case interview and a language test. It is quite long and tiring, but communication is clear and professional. All interviewers were polite, supportive, and genuinely helpful throughout the journey.
Questions d'entretien [1]
Question 1
Most of the questions focused on modern software engineering practices such as Domain-Driven Design (DDD), Test-Driven Development (TDD), microservices architecture, and DevOps practices. They asked how I apply these concepts in real projects and how I design scalable, maintainable systems in a production environment.
Live coding with java language. A bit hard with software principles. Some of project code is missing and required to complete. İnterviewers were polite and process was smooth. Takes 1 month

Entretien
I previously applied for an interview with my original CV, which included my international experience, and received a rejection. Later, when I changed the international experience to "freelance" and reduced the number of years of experience, they called me right away. The caller initially said things like, "Your experience is very valuable." I couldn't understand. I had written "freelance." During the technical interview, the team leader belittled some of my answers with his facial expressions. When he asked for the names of freelance companies, I told him I had worked abroad. This time, the team leader started asking more challenging questions. They could have at least sent me a case study, but thankfully, they didn't. Even the interviewers' facial expressions suggested a toxic, ego-intensive environment.

Question 1
What do you do to improve the performance of a machine learning model? What do you do in order to avoid from losing requests (let's say you don't have technologies like Kafka, RabbitMQ)?
