Wandering Merchant 🤔

On the way to the village of "Skuelevo", we stumbled upon a small forest, near which stood a merchant's stall.
The sign on it was peculiar: "Wisdom Shop".

Behind the counter stood the seller. His eyes were cunning, his hands grasping 🪙
The rogue sold us a whole four scrolls of wisdom.

Here is the list of those scrolls.
1. Logic and thinking in interviews
2. SQL block in interviews.
3. Product block (retention, cohorts) with simple analogies.
4. A/B tests and what they are eaten with.

We visited the merchant for a while, but it's time to know the honor.
Let's head to the village of "Skuelevo" and get new scrolls of knowledge 😎
