      Software Engineer Interview

      Aug 23, 2018
      Anonymous interview candidate
      No offer
      Negative experience

      Application

      I applied online. I interviewed at Mozilla in Aug 2018

      Interview

      Waste of time. Don't bother, they seem to be super disorganized and unprofessional. They contacted me for a phone interview, I gave them some times that work for me... didn't hear back from them for a week. They asked for more times, so I did this again. A week later, a different person contacts me to confirm the phone interview date/time. On the day I wait... they never phoned. A week later I get a rejection email saying they've reviewed my resume and don't like what I they saw... seems like they are just covering their butt for not contacting me when they said they would. A big waste of time. I can't believe how anyone would want to work for such a disrespectful company. Mozilla, if you don't improve your hiring staff nobody will ever want to join your company.

      Mozilla response

      Good morning, and thank you for taking the time to review our process, and for taking the time to apply to Mozilla. Based on your feedback, I was wondering if you would be willing to contact me with some further details about the process you experienced so I can take time to review where the breakdown in communication occurred. I apologize for your experience, and want to assure you that this is not part of our normal hiring process. My email is cstpierre@mozilla.com if you are willing to send me some more details. I would love to close the loop on this experience so we can ensure it doesn't happen again in the future. Thank you again, Chris St. Pierre Talent Specialist

      Difficult interview

      Application

      I applied through other source. The process took 4 weeks. I interviewed at Mozilla (California, MD)

      Interview

      It was not that much good or bad. The interview hiring process took too much long. After applying for role it took a month to get response for next stage interview.

      Average interview

      Application

      I applied through university. The process took 1 day. I interviewed at Mozilla (Toronto, ON) in Feb 2025

      Interview

      The interview process was in the form of a behavioural part and a technical part, similar to any other software engineering role. It was two hours. They are strict with their scheduling, so be ready to interview fast.
