Dmytro Kovalenko

Dmytro provided an excellent mentorship experience. During our consultation, he walked me through the entire interview process, explaining each stage in detail and what to expect. We also had our first mock interview session, which was incredibly valuable — it helped me realistically assess my current level and identify areas for improvement. His feedback was professional, constructive, and actionable. I received specific advice that I will definitely apply in my real interviews. Additionally, after the CV review session, my resume became significantly more polished and professional. I highly appreciate Dmytro's structured approach and his ability to share practical insights from real interview experience. Looking forward to continuing this mentorship.

I am very satisfied with my session with Dmytro. He provided a deep and engaging problem that was perfect for my preparation. Even though I didn't fully solve it during the mock, the detailed breakdown and the subsequent work on similar scenarios gave me a massive confidence boost for my actual interviews. Dmytro’s feedback was precise and highly actionable. I applied his suggestions during my real technical screening, which helped me feel in control and succeed. Beyond his exceptional technical expertise, Dmytro is a very pleasant and professional interlocutor. I highly recommend him as a mentor for anyone preparing for top-tier tech companies.

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.
