At least here in the US, most software engineers have had fairly extensive math education due to the excessive math requirements of CS degree programs

I don't think a CS degree is at all necessary to get an entry-level position at a tech company as a developer. If you have the knowledge requisite to the job that needs to get done, and can prove it with your portfolio, it's definitely possible to get hired. Speaking very generally, of course. It completely depends on the field and the industry. A defense contractor will have different hiring practices and requirements than a Silicon Valley startup.

In my industry, which is more in the latter category, I think it's easier to get hired with a CS degree, since it essentially stands in for work experience or is (in some cases) in lieu of a (real-world) portfolio, but you're likely going to get the same entry-level position as somebody as somebody with CS degree and equivalent experience or evidence of knowledge.

I obviously can't speak for every company, but I do feel that mine would rather hire somebody with the same experience as a CS major, but who doesn't have a CS degree (but still has some other college degree), since it (possibly, not necessarily) demonstrates an independent drive and passion for the work combined with unique skill-sets that might otherwise not be present. It's easy to demonstrate software development skills by pointing to your portfolio sand saying "I built these things, look at the code, you can see that I understand what I'm doing." It's difficult, however, to convince people in a 45-60 minute interview that you're easy to work with, invested in your work, have a sense of what it means to be part of a company and build products that sell, might have potential management or team lead skills down the road, are naturally curious and enjoy challenges, etc.

Many tech fields are predicted to grow at a steady clip, and companies are going to start tapping more and more into non-traditional applicant pools and trying out different kinds of employees to see what works.
