Over 250 tech industry leaders were asked which skills are in highest demand at their companies. Here's what they said.

Recruiters are increasingly turning to online tools to find potential hires, with 67% of respondents saying they use hiring portals like Monster and Zip Recruiter and 62% saying they advertise job listings on social media, both up from last year.

The most frequent channel for job placements, however, is employee referrals, which 73% of tech companies said they use to find potential hires.

Working as an intern can also prove a successful path to getting hired, but only sometimes: 56% of respondents said they look to internship pools to find qualified candidates for employment.

Once they've successfully recruited top talent, tech companies rely on non-salary benefits — both traditional and out-of-the-box — to keep workers around.

Health insurance is the number one benefit cited, with 91% of respondents ranking it as very important, followed by cash bonuses (89%, paid time off (88%), and flexible work arrangements (85%).

Tech companies are known to offer nontraditional perks to entice employees, which the survey confirmed: 88% of respondents said they offered out-of-the-box incentives, including planned recreational activities, open concept workspaces, gym memberships, and free food.

New technology like more sophisticated software, artificial intelligence, and robotics could change the landscape of the tech industry in the near future.

However, 57% of tech leaders who took the survey said they do not anticipate their company will displace workers due to automation or other advancements in the next five years.

Of the 29% who answered "yes" when asked if they expect some of their employees to be displaced in the coming years, two-thirds said they plan to train those employees new skills and retain them at the company — a 16-point increase from those who answered "yes" in 2018.

The CTA survey also asked tech leaders to detail specific challenges they expect to face when it comes to hiring new employees.

One of the most common concerns was the growing need for employees with "multi-knowledge" of disparate fields who can excel with both technical know-how and softer skills like emotional intelligence.

Respondents also noted that there's a disconnect between new hires, who may be coming directly from education programs, and managers who expect a certain level of real-world work experience.
