I applied through a recruiter. I interviewed at Trendyol (Istanbul) in Nov 2025
Interview
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.
Interview questions [1]
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)?
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
I applied online. The process took 2 weeks. I interviewed at Trendyol (Istanbul) in Jan 2026
Interview
The interview was generally focused on assessing my proficiency in the skills and knowledge required to perform the tasks listed in my CV. Live coding wasn't included in the first stage, but it will be a live coding session lasting approximately two hours in the second stage.
