What is one technique to improve coding skills mentioned for candidates?

Participating in coding challenges is an effective technique to improve coding skills because it provides practical experience in problem-solving and algorithm development under time constraints. These challenges often simulate real-world scenarios where developers must think critically and creatively to devise efficient solutions. Engaging in these activities not only helps candidates refine their coding abilities but also allows them to learn new techniques and approaches from others in the coding community. Additionally, coding challenges can enhance familiarity with various programming languages and frameworks, which is valuable for career development in software engineering.

In contrast, avoiding collaboration with peers restricts opportunities for learning from others and sharing knowledge, which is essential for growth in programming. Limiting practice to theoretical exercises may result in a lack of hands-on experience, making it difficult to apply learned concepts in practical situations. Focusing solely on advanced topics can lead to gaps in foundational knowledge, potentially hindering overall skill development.
