So, I am a CS student and recently sat down and applied to 400 internships in a sitting. 10 of them wanted alarming detail of my personal life. I'm sure it was all optional. However, questions varied from my sexuality to asking if I am homosexual or transgender. How is that relevant to working in any capacity? Asking for race/disability is pushing it, but to ask about something that deeply personal? Most of these fields do not have an option simply not to mark anything, only giving "Not disclosing" or something like that. That gives the reviewer the ability to infer and introduce bias. I cannot imagine how individuals who have not come to terms with things yet feel about this. Why is this in practice?
Edit: for those interested, I had about 200 jobs saved on linkedin I scoured for the day before and several lists I went through. I live in the United States. I use Chrome and I made sure my resume passed through an ATS with no problem.
