Mozilla – Why Work For Us?

Here at Mozilla, we are a group that works to make the Internet secure and free for you, the user.  Create, collaborate, revolutionize.

At Mozilla, we’re a global community of technologists, thinkers and builders working together to keep the Internet alive and accessible, so people worldwide can be informed contributors and creators of the Web. We believe this act of human collaboration across an open platform is essential to individual growth and our collective future.

    I have been working at Mozilla full-time (More than 3 years)


    The mission is real. Not pure but more real than most companies. Very remote friendly, engaging, flexible, supportive, and challenging.


    Mozilla has been through some growing pains, both in terms of employee size and direction. However, I honestly feel many of those pains have been mitigated.

    Advice to Management

    Keep up with recent (2017) direction. Make the fastest, most powerful, and beautiful browser on the market so that the world is a little bit more personal, free, and private. Sell the browser rather than the mission in order to achieve the mission.

    I applied through an employee referral. I interviewed at Mozilla.


    I was referred by a friend and then approached by recruiter who sent a quiz which had one Python question and one question about data science. I didnt like the part that they didnt give any information of what to expect in the online test
