Does anyone have more opinions on this?

I'm a coding boot camp dev with a few years of experience at startups and half of my resume consists of online MOOCS (Udacity's machine learning, Udacity's Linear Algebra, Fast.ai's deep learning, and Cloud Academy's Certified AWS Developer)

I'm curious as to what HR from Big Tech companies and small startups think about a resume filled with MOOCs like this.

I hire for a small startup, so maybe this isn't how it works at the big companies, but I certainly wouldn't dock points for this. I think it shows initiative, and at worst I wouldn't care one way or the other.

The only way I could imagine it being a red flag is that sometimes people put things on their resumes that aren't real accomplishments (like things they did in high school, or the fact that they know how to use MS Word) and it makes me wonder if there are so few worthwhile things for them to talk about that they use filler like that. But even then I pretty much just ignore it.

I don't hire engineers, but I am one. I've never heard this advice about not putting MOOCs on your resume, and if I were hiring, I would likely consider any MOOC (with a decent grade if applicable) to be better than nothing. Can the OP of the comment say more about the reasoning?

Am OP of comment, I believe the reasoning is that the quality of MOOCs varies wildly and there is often no way to confirm that a student actually completed the content or how well they did? Another reason could be that the sheer number of MOOCs that a student might take would just add noise to your resume?

I'm not sure that's accurate, but I've had many people tell me to avoid putting anything about MOOCs on a resume.
