We distributed the survey via targeted ads on Facebook, Twitter, and LinkedIn and via company channels (panel respondents and the @intellijidea account in Twitter). We collected 400 complete and valid responses from the US, Germany, and UK via different advertising. The rest of the respondents were recruited from other countries via company channels.

Some bias is likely present because JetBrains users may have been more willing on average to complete the survey in advertising channels, and because we’ve included JetBrains followers in the sample.

The raw survey data are available for your perusal.

Learning Tips & tricks

Stay determined

Software development is an enormous area so the learning process might become tough just because of the amount of available information. Don’t take it too hard on yourself: you face difficulties because there’s so much to learn, not because you’re not smart enough. If you ever consider quitting, do it because you’re no longer interested. Otherwise, believe in yourself and keep going!

Begin with a project

I suggest to come up with a challenging project regardless of how impossible it might seem - automatic watering system, budgeting application, chatbot, etc.! An exciting task inspires you to learn and provides an excellent hands-on practice.


While facing a complex topic, you might be tempted to skip it. Stay determined! Consider going through earlier themes to look for missing details. Otherwise, think about alternative solutions that may help you overcome difficulties.

Seek help

It’s always OK to ask for advice from mentors while learning computer science (and even later when working in industry). An outsider’s opinion is helpful to get around a challenge. Discussions with colleagues prompt you to come with a fresh way to fix a problem you wouldn’t beat on your own.


Try educational puzzles like CheckIO, CodinGame, and others. It’s a good way to see algorithms in action—all while beating monsters and earning points.

Put together a portfolio

Every project you do is an excellent addition to the portfolio. Get familiar with version control systems and put your code out there. Your best resume is an active GitHub account.
