I had upcoming Experience/Behavior and System Design interviews, but I didn't have experience with such interviews at big companies. I needed support with preparation, and fortunately, Dmytro agreed to help me. We reviewed and improved my CV to make it more presentable, and we also did a few mock interviews for both Behavior and System Design. As a result, I gained a clear understanding of what the interview process looks like, became more confident, and now know what to expect during real interviews. Dmytro was proactive—he always asked what I wanted to improve, gave feedback after each mock session, and provided a detailed description of my strengths and weaknesses. Thanks to this, I feel much more prepared and ready for real interviews.
