The 2021 edition of the CodinGame developer survey shines its spotlight on the reality of the developer's career, the rise in salary of some tech roles, and the general preference of developers and HRs when looking out for jobs/tech talents.

    CodinGame is a tech company providing a platform for developers to hone their coding skills by programming puzzles. It also provides a feature that connects developers with potential employers.

    Since 2018, the company has conducted an annual survey that asks developers and tech recruiters about their priorities, challenges, preferred technologies, and employment information.

    The 2021 edition of the CodinGame developer survey reveals trends in tech hirings, technologies, experience, demand, and recruitment of tech talents by analyzing results from over 15,000 developers and HR professionals across different geographic locations.

    Notable highlights

    Below are some of the notable highlights of the survey.


    33% of the survey respondents confirm that they are self-taught developers, learning from online resources, books, tutorials, YouTube, and so on. A cumulative 58.8% learned to code formally with 43% going to University and 15% saying that they learned at school. None of the respondents consider that they learned to code on the job.

    79% of tech recruiters agree that they already recruit coders with no formal academic background while 24% say they do that regularly.

    Similar to the 2021 StackOverflow developer survey, JavaScript keeps the lead as the most-known programming language followed by Java (59%) and Python (57%), with more than half of the survey respondents knowing how to code in at least one of these three languages. It is worth noting that the trio has kept the top three spots in this category locked since the first edition of the CodinGame developer survey.

    Developers using the languages, JavaScript (62%) and Java (59%) are in much higher demand compared to other languages like Python (48%), C (15%), or C++ (27%).


    Even though only 27.6% of the survey respondents say they know how to use React.js, the open-source javascript library is the most sought-after framework (59%) by recruiters. Node.js is the second most sought-after framework followed by Angular 2+(41%).

    Node.js (36%), React.js (28%), and .NET Core (23%) are the first, second, and third most popular frameworks in the category.

    CodinGame asked its HR respondents how many developers they planned on recruiting in 2021. 64% reveal that their companies are looking to hire up to 50 developers this year. 8% say they are looking to hire between 100 and 500 while 5% say over 500.

    Despite the difficulty and uncertainty, the pandemic threw into the general workforce, developers are confident of their ability to change jobs as a developer at any time. on a scale of 1 to 10, respondents of the survey chose an average answer of 7.

    When asked: Which positions do you think you’ll struggle to source/recruit in 2021?

    43% The survey HR respondents predict that they’ll struggle with hiring talents for the DevOps role. Backend developer (41%) and Fullstack developer (41%) follow.

    55% of the HR says candidate experience is what they will be willing to invest in in 2021. 49% chose talent retention and 43%, employer branding as their priorities for 2021.

    The survey also reveals that developers working in the Security industry are the highest-paid ($55,598) followed by Technology ($55,556), Insurance ($54,188), and Energy ($53,936) industries.

    Developers working in Pubic administration ($40,537) and IT services ($38,304) industries are the least-paid on the list.


    For the second year in a row, Software Architect ($74,585) is the highest paying tech position followed by Data Scientist ($55,695).

    44% of developers are looking for international job opportunities, 42% are looking for regional opportunities while 33% are willing to relocate nation/state-wide.

    The majority of developers (43%) prefer to work "few remote days a week", 24% want to work 100% remote and only 5% are willing to work 100% at the office.

    HR also supports this with 53% offering developers to work remotely "a few days a week", and 48% offering a 100% remote role.

    Developers say technical challenges, flexible working hours, and salary are the three things that matter to them most when considering a job offer. While HRs say technical challenges to solve, developers’ salary, and the company's tech stack are what they are looking out for when offering a job role.

    HR professionals listed finding qualified candidates, standing out from other companies, aligning with hiring manager's demands, and recruiting within tight timeframes as some of their biggest challenges when recruiting developers.


    Almost all developer respondents (78%) say LinkedIn is their go-to platform when looking for job opportunities. While HRs also majorly refer to LinkedIn when sourcing for developers, they also look into tech conferences to catch talents that suit their criteria.

    What do you dislike about the recruitment process?

    50% of developers say they dislike being targeted with irrelevant job offers, lack of feedback after interviews, irrelevant technical interview questions and exercises, and HR professionals who don’t understand tech.

    Developers and HR professionals prefer traditional face-to-face interviews, informal interviews, and live coding interviews. HRs appear to also like video conferencing interviews but developers dread it.

    45% of the survey respondents think remote tech interviews are gradually becoming the new standard while 48% think otherwise.

    Developers chose hands-on assessment tests with real coding questions, live coding interviews, and non-boring technical tests with challenges and/or games as their top 3 most preferred technical assessment processes.
