Raw coding ability is crucial in developer hiring, and assessing candidates through code reading is more effective than traditional coding interviews.
Résumé
When hiring developers, raw coding ability stands out as the most critical quality. The conventional method of coding interviews has drawbacks like memorization of answers and power imbalances. In contrast, having candidates read existing code offers a more insightful evaluation approach.
Reading code tests fundamental skills essential for developers' daily tasks. It requires remembering variables and generalizing code, which cannot be easily faked. This method is efficient as it provides quick insights into a candidate's programming skills compared to writing code. Moreover, reading puts candidates at ease and allows interviewers to adjust questions based on skill levels.
Practically, creating a set of exercises that progress in difficulty helps gauge candidates' abilities accurately. Calibration against colleagues ensures realistic expectations and question refinement. During interviews, emphasizing understanding over syntax knowledge and allowing candidates to debug their thinking are key aspects of the process.
The test involves predicting outputs from commented code lines, providing valuable insights into candidates' problem-solving approaches. While special coding skills are crucial, domain knowledge and cultural fit also play significant roles in the hiring process. Ultimately, regular practice by working on side projects is recommended to enhance coding skills for successful interviews.
