Let’s delve into the future of data science

 

HackerEarth: Can you give us a small bio of your journey in tech recruitment?

Ashutosh: I have been a part of recruitment in the data science field for nearly 14 years of my career and have recruited for successful startups (seed to Series D) and MNCs across levels (entry, junior, mid and senior management) and profiles including data analysts, data scientist, ML engineers, full stack developers, and DevOps/MLOps. I’ve also been part of campus recruitments in premier colleges (IITs, NITs, IIMs, and ISB) for roles in data science profiles, as well as the lateral hiring processes for experienced candidates for almost all my previous employers.

HackerEarth: In this era of mass layoffs, where do you see the data science and data analyst roles heading? Will there still be a need for this niche domain going forward?

Ashutosh: Mass layoffs depend on the health of a company and its measures to keep itself up and running and have less to do with any specific roles. Companies can cut all types of roles when it comes to survivability, but domains like data science and technology are some of the last ones to be axed since these are business-critical roles.

Let's delve into the future of data science

For instance, several of our clients, who are facing the pressures of recession, have been turning to data science to gather data-based insights on how to increase their revenue and save costs. Data science plays an important role in helping companies navigate and weather the recession storm.

We are a data-driven world, and data science will continue to be an in-demand domain. The demand for data science and data analysis professionals may fluctuate depending on economic conditions and the specific needs of individual organizations. It is important for professionals in these fields to stay up to date with the latest technologies and techniques, and to be proactive in seeking out new opportunities for growth and development.

HackerEarth: What are some of the mistakes/misconceptions (top 3) that you have seen recruiters or engineering managers make when hiring data scientists/data analysts?

Ashutosh: Firstly, focusing only on interviews and theoretical questions instead of looking for hands-on coding experience is a big mistake. The industry needs people who can not only understand algorithms but who can also code. It’s fairly easy to get a theoretical understanding of all data science algorithms from the internet without writing a single line of code, and we need to ensure we hire people who can actually build solutions.

Secondly, giving importance to degrees and background over expertise. Today, there’s a plethora of online degrees which require little effort for a diploma or master’s degree in data science – one can get a degree from Indian or international colleges for ~USD 4000. Some of the best data science professionals we’ve worked with have unrelated degrees and have learned everything by themselves – either from online courses, Kaggle, blogs, or self-training.

Lastly, every data-related skill cannot be equated with data science and AI. The latter’s expanse is wide and complex – from simpler tasks like data entry, to intermediate ones like analysis, visualization, and insights, and to the more advanced machine learning models and AI algorithms. Often, roles are clubbed as ‘data scientist’ simply because of such loose definitions of these terms. You don’t need to hire a data scientist when you may actually need a data analyst.

HackerEarth: How do you see the new technologies like AI, ML, and quantum computing affect the field of data science?

Ashutosh: AI, machine learning, and quantum computing are all rapidly advancing technologies that have a significant impact on data science. AI and machine learning are enabling data scientists to develop more advanced algorithms and models that can analyze and interpret data more effectively, while quantum computing is providing the computing power necessary to process and analyze large amounts of data quickly and accurately. These technologies are also helping automate many of the tasks that were previously done manually, which is making data analysis more efficient and accessible. Overall, these new technologies are helping drive significant advances in the field of data science and are likely to continue to do so in the future.

HackerEarth: How would you recommend that data scientists upskill themselves to cope with the current and upcoming changes in the economy and the tech world?

Ashutosh: As a data scientist, it is important to continually upskill and stay current with the latest developments in the field. Here are a few ways data scientists can upskill themselves:

  • Stay updated on the latest tools and technologies: Data science is a rapidly evolving field, and new tools and technologies are constantly being developed. There are new algorithms in the domain of Deep Learning, Reinforcement Learning, Transfer Learning, LightGBM, GANs, Transformers, large language models, and Explainable AI to name a few. There are new tools and frameworks in the industry like Airflow, Horovod, Petastorm, etc. developed by companies like Facebook and Uber, which have been made open source. There are also AutoML, ETL tools, visualization tools, cloud enablement tools, collaboration, and project management tools (like Asana and Trello). Keep abreast of these advancements and use them effectively in your work.
  • Learn new programming languages and frameworks: As a data scientist, you’ll need to be proficient in at least one programming language, such as Python or R. It is also useful to learn additional languages and frameworks such as SQL, Julia, or TensorFlow.
  • Enhance your machine learning skills: Machine learning is a key aspect of data science, and it’s important to have a strong foundation in this area. There are many online courses and resources available to help you learn machine learning and apply it to real-world problems.
