> It is much easier for product designers and product managers to pass interviews. You can see their work product.
You don't see any more work of a product manager than of an engineer. What you see is always the finished product, and you have no idea who contributed what parts. If the overall product that can be publicly experienced is good, then some engineers in that team seem to have been doing a good job. You won't easily know which ones - and you especially don't know whether a product manager on the team really a lot of influence on this or whether the products vision and execution was mostly driven by engineers.
And the second point:
> If you could review someone's code from their previous jobs, I think it would be quite easy to vet applicants. And it would be much easier to move from job to job.
Sometimes employers can - because candidates have open source code. But experience has shown that these datapoints are not used, and employers still fall back to the default process of assuming nothing and doing whiteboard/leetcode style interviews.
