Behind the code - The 2020 HackerEarth Developer Survey
Hello from our CEO The explosion of tech over the last decade has, quite literally, changed everything. It has changed how we live, how we work, how we interact with one another— in fact, it is difficult to find something that tech has not changed. It’s no surprise that organizations across the globe feel that there’s a tech talent shortage. But that shortage may be even more significant than you’d expected. According to a recent survey, the shortage of tech talent recorded today is at its highest level since 2008. Hence, it is imperative for recruiters and hiring managers to understand the developer landscape and understand the mindset of today’s tech workforce if they hope to meet their demand for tech talent.
One of the key changes that organizations need to do to hire better is to shift their focus from the traditional methods of recruiting to a skill-based hiring process. If we move beyond our current fixation on resumes or degrees and include all the postsecondary pathways at our disposal, far more options will emerge. Skill-based hiring practices can help you cut down recruiting costs and time-to-hire, improve diversity, fill open positions faster, and find the right tech talent your organization needs in a tight labor market. At HackerEarth, we have a 4 million strong developer community and our mission is to match them to the right opportunities. To continue supporting our mission, we are very excited to bring to you The 2020 HackerEarth Developer Survey. For the first time ever, HackerEarth is sharing the response gathered by surveying 16,000+ developers from across 76 countries. We believe the data and insights provided in the survey will thoroughly help recruiters to understand the developer ecosystem better, adopt a skill-based hiring approach, and tap into a highly coveted market of stellar tech talent. Additionally, this survey will provide an opportunity for developers to gauge an understanding of what the market looks like today, learn what’s trending, and how to upskill themselves. I look forward to seeing you use this data to further your technical hiring efforts. Thank you for your time! Sachin Gupta Co-Founder and CEO HackerEarth
What can you expect from this report? The 2020 HackerEarth Developer Survey is an annual snapshot of the most hard-to-recruit and highly-coveted talent out there. This report highlights the priorities and concerns of developers (students and working professionals) around the world. The survey comprised more than 16,000 participants, with women comprising more than 20% of respondents. The report condenses and distills down the results into actionable insights that pave the way for skill-based hiring. Also, it provides developers with everything they need to know to upskill themselves, learn new ones, and have fun (obviously!)

take-home coding interviews any day! Irrespective of the
YoE, most developers prefer live video
challenges interviews to whiteboard interviews. This
could be because the whiteboard
approach makes use of a potentially
outdated scenario to test a developer’s
skill.
Live video interviews, on the other hand,
allow candidates to develop and compile
code in real-time and gives hiring
managers a chance to test them for job
readiness.

A community of 4 million developers globally uses our platform to hone their skills and learn from each other. Hence, to identify trends in the developer community, we surveyed developers (students and working professionals) worldwide to get their valuable feedback. Our understanding was derived from several developer responses around the globe This study presents the results of a survey we conducted in January 2020 to February 2020. We received a total of 16,655 responses from developers across 76 countries. Our approach was comprehensive We tried to cover all aspects that have an impact on the developer community, including but not limited to, the most sought-after programming language, the most preferred operating system, the most preferred medium for finding new jobs, and more. Our in-house team of experts analyzed the results. Percentages may not always add to 100% due to rounding.
