Yeah, r/Mozilla can only be accessed with a Reddit account apparently, so I report the text here:

«Hired to work on recruiting contract. They told me 15 to 20 hours per week but said if the work increased they would absolutely cover my hours. I was putting in 40 hours per week at one point because the job postings had more than 1000 applicants each. The VP role had 1700 applicants. They had me interview 65 candidates. 65!!! Terrible candidate experience. For one of the role there was 5500 applicants. I had a total of 7 roles to screen, document and process through the ATS under 20 hours a week. DO THE MATH. It is not humanly possible. They continued giving me more work but when it came time to pay me they refused and made me change the invoice and resubmit the hours. On top of that they claimed that I had shared confidential information (NOT TRUE and NO PROOF) and ended my contract when I spoke up. Horrible people. Took advantage of me. The values they speak of are just lip service. HR is an insult to the practice. Never in my work history have I have been treated so badly. »

Of course I can't know if it's true
