This is followed by knowledge of statistics (80.6% of respondents) and basic ML (75.6% of respondents). More than three in four professionals claimed that basic ML understanding is a must-have skill for a career in data science and is indicative of how far we have come in the field.

Popular programming languages amongst data scientists

Out of the host of programming languages, 90% data science professionals use Python as their choice for statistical modelling.

Beyond that, SQL and R are preferred by 52.8% and 38.3% of the respondents, respectively.

The use of SQL (68.4%) is highest in retail, CPG, and ecommerce, followed by IT at 62.9%. R is the most commonly used programming language in the pharma and healthcare sector, with three in five (60%) professionals claiming they use it for statistical modelling.

Top data visualisation tools

Despite all the technological advancements in data science, the use of MS Excel remains high with 2 in 3 (63.3%) professionals using it regularly. This is followed by Tableau (56.7%), Power BI (43.9%), and QlikView (12.2%).

As many as 70% of professionals working in BFSI upskill in MLOps.  Another 70% and 60% of professionals in the pharma & health sector are interested in learning transformer and computer vision as core skills.

“The data science domain is on track to change the nature of jobs, now and in the future. For professionals looking to thrive in a digital-driven future, setting a foundation for the right data science skills needs to start now to weather the changes that are to come. This domain has impacted the way companies and businesses function and professionals who upskill in this field have a chance to become prime candidates in lucrative industries,” Hari Krishnan Nair, co-founder, Great Learning said.

“Through this survey, we aim to help recruiters, industry leaders, policymakers, companies, and data science experts/aspirants gain an in-depth understanding of the most impactful languages, models, tools, skills, upskilling approaches and recruiter perspective that is needed to make structured and informed decisions,” he added.

The report has been developed after primary research through a survey conducted amongst data scientists and leading AI/ML practitioners. This was complemented by direct discussions with job-seekers to understand and gauge their perspective on the in-demand skills in this domain.
