Qoolli Bewertungen 

I'd like to share my experience working with this company. I'll start with the manager, Olga—she's a very professional, clear, communicative, and flexible professional. We can negotiate specific issues. The team is experienced and reliable; you don't need to pressure them; they know their business very well. Overall, I highly recommend them!

I am currently studying at Qoolli Academy in the software testing course. Even though my training is still in progress, it is already clear that the approach here is very thorough: a lot of theory, work with documentation, and practical examples. This helps not just to memorize the material but to truly understand how the testing process works.

What I especially value is that Qoolli Academy teaches us to look at a product from the client’s perspective and pay attention to details. This builds a professional mindset from the very beginning. I am confident that this level of training reflects the high quality of work the whole team delivers.

I would like to share my personal experience with Qoolli, where I am currently studying QA.

I chose this academy because the instructor, Olga, has outstanding expertise in manual testing, backed by many years of practical experience. Her most recent role was at the Ministry of Foreign Affairs of the Netherlands — a position that demanded not only deep professional knowledge in QA, but also fluency in Dutch.

Since I now live in the Netherlands and am navigating similar challenges, I found her career path and leadership experience especially inspiring.

Olga stands out for her ability to structure complex tasks, organize workflows efficiently, and approach problem-solving with logic and consistency.

What I value most, however, is her leadership style. Managing a group of about 40 students, she skillfully resolves misunderstandings, supports open communication, and creates a collaborative, relaxed atmosphere where everyone feels comfortable. Her ability to defuse tension and keep the group united is something I truly admire.

I’d like to share my experience working with Olha as a teacher.

My name is Oleksandr, and I’m one of the students at Qoolli. Before joining Qoolli’s free course, I had no idea what QA testing was — in fact, I was completely unfamiliar with the IT field. But from the very first lecture, things started to change. The learning materials were clearly structured and focused only on what really mattered, which helped me quickly get into the process and start applying what I learned in practice.

After just one lesson, we were already able to find bugs on our own and write our first bug reports. Throughout the lectures, there were plenty of visual examples that were easy to understand — even for a complete beginner like me.

Of course, there were moments when I didn’t understand something right away. But whenever anything was unclear, Olha and her team were always available — either offering personal explanations or hosting extra group Q&A sessions. That level of support made a big difference.

I’m still studying, and I believe that learning is a continuous process — essential for growth and development. And with Olha and her team, this feels achievable.

What really stands out to me is Olha’s responsible, thoughtful approach to teaching and her openness to personal communication. The consistent feedback I receive from her and the team makes me feel like part of a community that’s always ready to help.
I highly recommend Olha’s course and the Qoolli program to anyone interested in starting a career in QA testing. The structured approach and strong support make it an excellent choice for beginners.

I study at Qoolli Academy and am happy with my choice. The material is presented in an accessible and interesting way, there are many practical tasks that help consolidate knowledge. The teacher is attentive and involved, always answers questions and explains difficult moments. It is clear that she is interested in the success of students

My name is Maksym, and I’m a copywriter. Olha – the founder of Qoolli – reached out to me with a request for the text for her future website.

At that point, she already had two versions of the copy. I did an audit, we discussed everything, and decided to make a number of significant changes.

Olha is one of those rare clients who know how to trust professionals, so the work went smoothly and quickly.

To write the text, I needed a lot of details. I asked questions in waves – first one thing, then another. Olha replied clearly, quickly, and to the point – both in writing and during our video calls. It was obvious she’s a very focused and goal-oriented person. In my opinion, it's exactly people like her who create outstanding projects.

At the same time, Olha was coordinating with a designer – juggling both copy and visuals. That’s no easy task. Managing the process is clearly one of her strengths. I’m sure if it were all up to her, the site would’ve been finished even faster.

Of course, it was not without edits. But they were so tactful, reasonable and appropriate that I, as a copywriter, did not have a single gram of irritation. Moreover, she calmly discussed my design ideas as well.

I'm sure that Olha shows the same qualities in her work with clients – attention to detail, respect for experts, ability to take on the process. I am calm for her clients – they are in good hands!
