Throughout the interview, it becomes clear that not only theoretical knowledge is being assessed, but also depth of understanding, reasoning skills, the ability to handle unconventional questions, and to calmly respond to the interviewer’s clarifications. In the end, the candidate’s strengths and weaknesses are reviewed, common gaps among beginner developers are discussed, and recommendations are given on what to focus on in learning in order to perform more confidently in real interviews.
