with CodeHorizon simulations

I want to share my impressions))) The task from a short table to a long table fits marvelously into the test solutions of problems (the technique itself). The last test very much liked the employer, I think it's because of the last task, in which this technique was needed. They are ready for an interview, and even promised a salary of 150, but I chickened out and will probably agree to go to Otkritie Bank. So I want to say thank you for this task 👍👍👍👍

Good evening! I'm going through the block about sql now, I've reached the joins so far. And I want to say that your tasks are interesting to solve, they require turning on your head. The tables are just like at work 😂 and now I know why they are like that).

I'm with the news!

Two more employers in the queue) You won't believe it )

I also advertise you as much as possible to all my friends, colleagues and acquaintances. Since I found a job only thanks to your course).

In general I wanted to write to you that I like the atmosphere of training - very informal, and cozy and kayfovo that there is no opposition between students and teachers and some arrogance and condescension, as in other courses!

Very powerful course! Pumping just unbelievable! Studying the course changed my logic completely, requests became easier and more optimal, I am very happy that I am learning from you!

Initially, I had no practical experience in SQL. The simulator allowed me to look at this topic a little differently and gain confidence that this is my topic. When working in the simulator, working with the database became more interesting. I began to delve into the process more consciously. I also learned a lot of new things and generally understood what a data analyst does.

Very useful platform!!!

Your service is very cool, thank you for it

Just going through this Simulator so far, but I like it. Learned a lot of new things. And this course is developing, all new parts are added, which is generally good. Adequate support, good reviews.

Thank YOU! was the first task, and I will say that the experience gained from you has borne fruit!

I confirm. I'm going through it myself. There are a lot of useful things in the course. Plus, the presentation of the material is clear. I also finished 6 blocks.

Here are the cool tasks, you get a jump on the real ones, which will be at work. I bought access ordinary, not premium, very cool tasks, and not detached from reality, and that you will solve in combat conditions

I, by the way, recently went through a good Simulator, they have a very interesting presentation, lots of practical challenges

And so, the course is great! Thanks to the 4th module, I finally understood how to evaluate a business by metrics

Yandex Praktikum is not so juicy and simple in its presentation.

I join the positive reviews, really simulator pumps knowledge in sql, and most importantly that without detachment from reality, that is, you immediately apply it on real tasks from the workflow. Well and feedback personalized of course bribes at once, well even by this chat it is clear what it will be))))

And it's also interesting you record videos, I when I watch and when I see something, I can think: "I wonder what will happen if you do this or that" or "the result looks somehow not very good" and often you immediately explain or say that the result is not very good, let's make it beautiful)) it's just magic!

Yeah, I really like my own big query with joins, which even has a subquery. I used to unload only one select from different tables and then only merge them. Somehow after your lectures it becomes clearer in my head what and how I can do it
