    Application

    I applied online. The process took 2+ monthsinterviewed at Mozilla in January 2015.

    Interview

    The first round was a coding interview via phone and an online editor. First few questions were fairly simple, the last one was a little bit more challenging where I got stuck. The interviewer was very nice and guided me to a solution.

    The second round was all based on my resume, my previous experience, and course projects etc.. Then I was required to explain some technical details I learnt from the course, where I got really nervous and stuck for a while. But it was OK in total.

    The interviewer were all excellent engineers and very kind and friendly. In all I quite enjoyed the whole process.

    I applied through college or university. The process took 2 weeksinterviewed at Mozilla in December 2014.

    Interview

    I had three interviews total and the whole process went very smoothly and promptly for me. The first interview was a skype interview with someone who talked to me about my general interests in software engineering and gave me a simple coding question. The next round was someone on the mobile team who was more behavioral in style and also asked me high level questions about mobile development and asked me how I would implement solutions to specific situations (e.g. how to change a link color, live, and based on database info). The last round was a technical interview in the form of a problem that would be similar to what I would face during the internship. I really liked everyone and I look forward to working at Mozilla this summer!

    I applied online. The process took 3 weeksinterviewed at Mozilla in October 2014.

    Interview

    I had an excellent interview experience. My recruiting coordinator did a very great job at follow-up, and made sure I was very well informed. I was asked to come in for an on-site interview, and had a great time speaking with the whole team. The only part of my interview experience that did not go as well was when I interviewed with one of their senior recruiters. At the end of the interview, they had mentioned that they will move forth with me. The next day, I received a rejection email. I don't mind not receiving the job, but it was a little disheartening thinking that I had received the job, when in fact I was still in the selection process.

    I applied online. The process took 3 weeksinterviewed at Mozilla (San Francisco, CA) in September 2014.

    Interview

    A phone interview followed by a 2.5 hour face to face interview. I was asked to meet with a separate team as there were two available roles. Although I felt the interviews went well as I was well prepared, I could tell one of the managers did not like one of my answers and thought it too 'recruiter-y'. The role description was vague and the team was also a big vague on what they were looking for. All interviewers were very friendly albeit a bit unorganized.
