I highly recommend this course! Dima is great instructor. He explains very well. He helped me a lot with coding challenges. Constantly in touch with students and very responsive. Thanks again Dima for your course!

I am very glad that I took this course! Dmitry is a wonderful instructor: passionate and knowledgeable about Java, patient with students, responsive and prompt to questions in between sessions. I wish I knew about his instructions before, I would have loved to take a "Java, introduction to basics" course as well with Dmitry. I highly recommend this course to get you started in Java coding challenges!

Dmitry is an excellent mentor with a very easy to follow teaching technique. This course will introduce you to a more professional way of solving coding challenges and will give you a deeper understanding of complex Java concepts. Highly recommend!

I took the Coding challenge classes to get myself prepared for the coding interviews. I found this course is really helpful. The class contents are very well designed, very easy to follow and understand. This course can help to get well prepared for the coding interviews. The class lessons are very effective. If someone follows the classes consistently, should be able to attend any coding interview with confidence. The class really boosts up the confidence level. The course teacher is very knowledgeable. He explains complex things in a way that is easy to understand. I highly recommend this coding challenge course for anyone who is interested to get well prepared for coding interviews.

I started studying at Portnov School because three of my friends recommended it to me, and now, when I graduated and found a job, I will recommend it to my other friends too! I actually already have some friends who are studying or just graduated as I did. When I was studying at Portnov School I regretted starting it, because often there were times when I had difficulties understanding some things (especially Java) or just finding enough time to complete homework and catch up with others. Now, when I got 2 job offers (and lots of final interviews canceled because of already having 2 great offers), there is only 1 thing I regret: I regret that I hadn’t started studying much sooner! 95% of all questions that I got on interviews were discussed during our classes and internship so I was very well prepared to answer them, thanks to our teachers. I really appreciate the hard work of all the teachers! I got lots of phone calls from recruiters because my job market resume from the school was very well polished! I am excited to start my job soon and I highly recommend taking this course ASAP if you want to change your life and get a better job!
