Online learning for an edge in your next role?

Hi All,

I'm a Enterprise AE in SaaS who got caught in a reduction in force at my last company.

I am finding myself with a few unexpected free days on my hands and am looking to use it to up level my skills for the new year.

What are some brief no to low cost online courses that I can invest in to make myself more appealing as I apply for my next role?

Thanks in advance!
