Why does Devsisters' server engineering track include a coding interview?

Devsisters' server engineering track conducts both an oral interview and a coding interview to verify technical competency. The coding interview allows web search with no restrictions on language or framework, providing an environment where candidates can perform at their best.

Interviewers focus more on the process of defining and solving the problem than on simply arriving at the correct answer. They mainly check what thought process the candidate goes through to reach a solution, and how well the candidate understands and can improve the code they wrote.

The key evaluation factors are as follows:

• Problem-solving process: the flow of thinking and how technical obstacles are overcome
• Code understanding and improvement: the ability to identify the code's limitations and communicate about it from a maintainability perspective

As actual examples, a problem implementing a search tool using multi-threading is used to evaluate the ability to apply technology and understanding of concurrent programming, while a problem implementing an API server is used to check requirements definition and structural design skills.
