Spent six months on Python video courses. Everything made sense in lectures, but sitting down to write code from scratch never worked. Here you write from task one. On harder tasks I'd get stuck, but premium unlocks reference solutions, and I'd compare my janky code to the canonical version line by line. A month in, I wrote a script at work that builds a report from 30 CSV files.

Bombed a tech interview on a simple dictionary task, brain just shut down under stress. Worked through interview tasks from Yandex and Avito in the trainer, at the next interview I got almost the same problem and had an offer within a week.

Moved from manual QA to development, and toy tasks about factorials and Fibonacci were driving me crazy. In the trainer it's JSON parsing, CSV processing, API work, exactly what I do at my job, just without deadlines and the fear of breaking prod.
