For AWS, I was bombarded with recruiters (and still am as its listed) after receiving the associates level certification.
I believe I was hired at the time solely to meet partner level certification quotas of my current company as they definitely didn't need more headcount and there wasn't much to do at the time.
The whole thing really grinds my gears though and I wish it wasn't a necessary evil for me to pursue more of them. I think services such as acloudguru and the like devalued them from a technical perspective, but Amazon puts their finger on the scale with partner requirements keeping them relevant.
