An increasing number of organizations across industries have realized that business success, to a significant extent, is characterized by a firm's ability to gather, store, analyze, and productize data faster than its competition. Consequently, this big data revolution has increased the demand for data scientists/engineers with R programming, Hadoop, Python, and other such data skills.

This projection underscores the underlying need for data scientists who can explore, analyze, model, and visualize data for businesses that base their operations on it. Therefore, excellent data science skills are essential for anyone envisioning a flourishing career in the sector. Furthermore, many data engineers, scientists, machine learning engineers, etc., prefer R over other languages owing to its usefulness and adaptability in data-related tasks. Interestingly, tech professionals can utilize several packages and libraries that enhance R’s functionality and simplify the task of data professionals. Unsurprisingly, R professionals are well-paid in different industries and highly sought after.

While hiring dedicated data professionals to add value to the organization, you must use an R Skills Test to assess a candidate's domain knowledge and identify the best person for the role.
