Thank you for the video! I think what must be said is the non-techincal filter on job applications. Many recruiters/HR will be inundated with applications in these market conditions, so, why not offer yourself another reason to get put in the 'positive' pile.
Oh yeah, a very good point. Job market is a bit more challenging right now, so anything concrete to be able to show might just give you that edge. In that sense, even the lightweight free certificates you can do within few hours work. Probably not going to be the main decision factor, but just a little bit of extra on top.
