    Difficult Interview

    Application

    I applied online. The process took 3 weeksinterviewed at Mozilla (Mountain View, CA) in February 2014.

    Interview

    The process for me took around 3 weeks from when I put my applicaiton in and when I finished my interview. I heard from them in two weeks and then had the interview a week following that. My interviewer was great. When I was stuck on a problem, he pointed me in the right direction. I heard back shortly therafter with their decision.

    Difficult Interview

    Application

    I applied online. The process took 5 weeksinterviewed at Mozilla (Mountain View, CA) in February 2014.

    Interview

    One first interview with an engineer. No technical questions asked as I mentioned a bugfix into Firefox for Android.
    With his positive feedback I got two other interviews. The first was more technical with javascript questions. The second one was more overall knowledge.
    They all gave me positive feedback but due to the large amount of candidates this year (and given the fact I applied late, in january), they finally rejected my application after 2 weeks without news.

    Application

    I applied online. The process took 4+ weeksinterviewed at Mozilla (Mountain View, CA) in October 2013.

    Interview

    I was contacted approximately two weeks after applying online by a recruiter, who then scheduled me for a technical interview the following week. The whole process consisted of three technical interviews, and even though I did not pass the last round, I was assured by my recruiter that it was only three interviews.

    Difficult Interview

    Application

    I applied through an employee referral. The process took a year or moreinterviewed at Mozilla (Mountain View, CA) in April 2012.

    Interview

    The hiring process was long and painful, hr was completely unhelpful and employees have no ability to help in the process so they don't bother trying.

    At first an employee asked me for my resume, then it took hr about 3 months to contact me, then I was invited to visit the office during a work week and spoke to a director in person, so asked me to email him about it. So I emailed him and never got a response, so I figured they didn't want me. A few months later I started a new job and a week after starting the job I got a call from hr again, so I told them that I wanted to get at least one project done at the new job before leaving them and starting a new job. They told me to contact them when I was ready again. So about 4 months later I did that and didn't hear back.

    After a year or so someone else at the company asked me for my resume, and then I waited another 3 months for a phone call from hr, then I did 3 phone calls over the span of a couple of weeks. After this I was flown down to Mountain View for 5 1:1 interviews. About 3 weeks later I found out that I got the job. The whole process was over 2 years long, and I spent the entire time contributing code and reviewing add-ons on AMO in my free time for 10-30hrs a week on top of my full time job.

    The process took a dayinterviewed at Mozilla (Mountain View, CA) in April 2012.

    Interview

    30 minute screening call by a 'recruiter' followed by a generic rejection email that didn't indicate that a conversation ever took place. So in essence, even if you talk to them, they'll never stick their necks out far enough to even acknowledge ever speaking with a candidate in the first place.

    Application

    I applied in-person. The process took 1+ weekinterviewed at Mozilla (Mountain View, CA) in December 2011.

    Interview

    The interview process at Mozilla is refreshingly different. Instead of being asked a lot of technical details the interviewers did know what you do and instead ask you about what you can bring and what you want. Instead of just going through your CV I felt people really tried to understand you.

    I applied through a recruiter. The process took 1+ weekinterviewed at Mozilla (Mountain View, CA) in October 2011.

    Interview

    Three phone screens. Two with web developers, one with director of web development. A college recruiter helped set up all of my interviews after I talked to her at a barcamp and emailed a resume. My first interview went really well. I talked a lot about my projects, was asked a few simple questions about web development basics, and asked about their workflow. Mozilla has a very open and free culture and the people are very nice.

    Negotiation

    I was given a stack of papers and filled it out. Got to choose from a list of laptops. This is a good enough opportunity that I wouldn't bother to negotiate anything.

    Application

    I applied through a recruiter. The process took 4+ weeksinterviewed at Mozilla (Mountain View, CA) in August 2011.

    Interview

    Had multiple phone interviews.....4 if I remember correctly. Each of them went extremely well and the interviewers were very cordial. Some of the engineers grilled me a bit technically, but I expected that.

    After doing well on all phone interviews I was flown to Mountain View for several face-to-face interviews with different team members. Some of the interviews were with folks who had already interviewed me over the phone, but I also had a few with individuals from other groups. All interviews seemed to go very well. I was asked several technical questions dealing with different scenarios. I did very well technically.

    The engineering team took me to lunch and it was pleasant. After lunch it seemed that they rushed me through the rest of the process and got me back on my way home quickly.

    I received an email a few days later informing me that everyone thought highly of my experience and technical skill level but ultimately did not believe I was a fit for the team. They told me that was all the information they could give me. I am guessing it was because I was too conservative and too old for them.

    I even emailed one of the engineers a few days later asking him to give me some feedback on the interview so that I could work on any weaknesses. He did not even respond to me......very strange.

    Difficult Interview

    Application

    I applied online. The process took 2+ monthsinterviewed at Mozilla (Mountain View, CA) in July 2011.

    Interview

    Overall, the interview process went very smoothly. 4 phone interviews, 7 45 minute on-site interviews, and 1 lunch interview. Every single person I talked to friendly and highly open to questions I had. My interview process is summarized below.

    Upon initially submitting my resume to Mozilla Careers Website, I was contacted within a few days to setup an initial phone screening with the recruiter. This interview focused on no technical details, just questions about my interests in Software Quality Assurance. Next, the recruiter was interested in having me conduct a technical phone interview with one of the QA Engineers. This interview focused on questions on testing basics, manual testing vs. test automation, and some questions about my resume. I then had another phone interview with a QA manager, who targeted similar areas to the past interviewer along with asking a few software process questions. Then, I had a fourth phone interview with a QA Engineer who was a recent graduate of college. He focused on questions in open source community area. Next, I was flown out to Mountain View, CA with my flight, hotel, and transportation, and miscellaneous expenses covered. At this interview, I had 7 45 minute interviews and a lunch interview with some QA Engineers/Leads, QA Director, and a software development engineer. Questions in these interviews touched on a vast variety of topics, including quality assurance, my resume, technological knowledge, debugging, testing on desktop vs. mobile, etc. Upon finishing this on-site interview, I was contacted two weeks later with an offer.

    Didn't have negotiate, as I thought the offer given was excellent.
