Mozilla application questions — all 79, word for word
Mozilla hires through Greenhouse. Beyond name, email and CV, its application form asks 79 questions, 66 of them required. 10 of them are required, fixed-choice questions about your eligibility to work. A cover letter is optional.
260 roles were open when this was last checked, mostly in engineering and sales. The questions below are the form's own wording, not a paraphrase.

74 of the questions below are ones at most two of the 213 employers measured ask (median: 18), the least standard being “How many years have you personally managed a major gifts portfolio and been directly accountable for cultivating, soliciting, and securing gifts? Please count only major gifts experience, not your total years in fundraising or adjacent development roles.”.
The eligibility questions
These are required, and answered from a fixed list rather than in your own words: work authorisation, visa sponsorship or security clearance. Employers often use questions like these to filter applications automatically, but Greenhouse's public data does not say whether Mozilla does — so treat them as the answers most likely to matter, not as a verdict. Answer them honestly either way.

Before you apply
Have the answers to the required questions ready before you open the form — Mozilla's asks for 66 of them, and Greenhouse does not save a partial application by default. Settle the eligibility questions first — they are the ones with no room to elaborate, so knowing your answer before you start tells you whether the rest of the form is worth your time.
