An SME, or "Subject Matter Expert," refers to an individual who holds deep knowledge and experience in a specific field. For example, a senior Symfony developer may be considered an SME in backend development using Symfony, or a financial analyst might be seen as an SME in investment. In many hiring processes, after passing the HR interview, you will interview with an SME to accurately assess your specialized skills. Understanding the expected skills and knowledge of an SME in a job posting can help you prepare better for the interview; a task that the tool from roledecoder.com simplifies by analyzing the details of the Job Description.
