The interview was heavily focused on Object-Oriented Programming (OOP) and AdTech concepts. It was quite technical and conceptual, involving deep dives into fundamental principles, system design, and how these apply in real production environments. We discussed scalability, performance, and the trade-offs involved in making architectural choices.

Behavioral

The overall impression from the interview was negative. During the first stage, the Technical Recruiter behaved in an unprofessional and disrespectful manner. She raised her voice and spoke to me harshly, even though she did not know me personally. This attitude created an unpleasant and uncomfortable atmosphere, leaving me with a poor impression of both her professionalism and the company’s interview process.
