Lacking the necessary work experience, some newcomers make mistakes that, with a high level of interest, they could well have avoided. Artem Dmitriev has prepared a list of five typical mistakes that novice programmers encounter. It includes: incorrect choice of priorities, search for simple solutions, reluctance to leave the “comfort zone”, constant change of directions and incorrect positioning. If you are interested in the answer to the question of what exactly Artem meant in his list of programmer mistakes, we recommend setting aside a few minutes of your time to watch this video.

What level of English is needed to become a Junior Developer?

Without a sufficient level of English, a developer significantly narrows his opportunities for professional and career growth. And the point is not even that you can freely communicate via Zoom with a potential customer or employer from the United States, but that with poor English you may have difficulty studying technical documentation. And, of course, a good level of English in itself is always an additional plus in a resume. Don't worry if you're not up to the Advanced Level anyway. The creator of the YouTube channel About IT is confident that you can pass an interview in English with a much lower level of knowledge. To support this, the video blogger gives examples from his own experience.
