Developer recruitment platforms report seeing a sharp rise in the demand for data science-related IT skills.
The latest IT Skills Report by developer screening and interview platform DevSkiller recorded a 295% increase in the number of data science-related tasks recruiters were setting for candidates in the interview process during 2021.
Data analysis was seen in 32.69% of data science coding tests. "The rise in popularity of data science comes as little surprise given how valuable data has become to companies across the globe," said Jakub Kubryński, CEO at DevSkiller. "The number of tasks in our testing catalogue related to Data Science and Python grew in 2021 by 158.33% and 113.33% respectively."
DevSkiller's findings were based on 102,869 coding tests sent through the DevSkiller platform between 1 December 2020 and 1 December 2021.
The annual report, which is now in its fourth year, aims to capture hiring trends from the global tech industry by assessing the types of skills candidates are assessed on by recruiters.
Cybersecurity and QA (quality assurance) were also among the fastest-growing skills, along with programming language PHP, Scala and Blockchain.
DevSkiller said the appearance of cybersecurity on the list was no surprise given how quickly technology has advanced in recent years as companies digitise their platforms, products and services, leaving them with "constant new threats" to mitigate.
Between 2020 and 2021, 40% of coding test invitations were for junior developers, DevSkiller found, while 23.4% were for middle developers, and 36.6% for senior developers and engineers. Junior Python developers (54.78%) and junior data scientists (45.45%) were the candidates recruiters were most keen to hire – again, echoing the sharp jump in the need for professionals to make use of company data and make it profitable.
"Companies are spending big on building the right teams of data scientists who can help them grow more dynamically," the report said.
CodinGame and CoderPad's 2022 Tech Hiring Survey also identified data science as a profession for which demand greatly outstrips supply, along with DevOps and machine-learning specialists. As a result, employers will have to reassess both the salaries and benefits packages they offer employees if they hope to remain competitive.
A report by the UK's Royal Society in 2019 warned that demand for data scientists and data engineers had more than tripled over five years, leaving businesses "crying out for professionals to unlock the potential of new technologies", such as machine learning and artificial intelligence.
It also warned that the UK risked being left vulnerable to skills shortages unless "radical action" was taken to address the supply of data experts into the workforce
DevSkiller's report said the onus was on employers to secure what little talent there was available by drawing up competitive salary and benefits packages, and figuring out a USP that would prevent candidates from being swayed by rival companies.
"Hiring managers will also have to come up with more creative ways to help their company's brand to stand out and to offer candidates something unique...More than ever, companies are doing all they can to keep up employee morale and job satisfaction," the report read.
"Invariably the companies that can come up with the most creative solutions for remote-work employee satisfaction, will be the ones who not only attract but also retain the best tech talent going forward."
