Artificial intelligence and data science jobs top the list of the most difficult IT hires, but other skills are tough to find, according to an article in CIO. However, the trick to filling tough-to-fill roles begins with the job description. “It might seem like a good idea to make job requirements as exhaustive as possible, but in reality, that may turn off qualified candidates who would be great for the job,” Jason Hayman, market research manager at IT staffing firm TEKsystems, told CIO. “To combat this we recommend companies work with IT managers, line-level staff and recruiting experts to put together a realistic job description to widen the candidate pool.”
