What’s the difference between the senior and mid level SWE interviews at Capital One?

Capital One's "Senior Associate SWE" is equivalent to the Google entry level L3 and Facebook entry level E3. "Principal Associate" is more like Google mid level L4 and Facebook mid level E4. The bar is higher but Capital One doesn't evaluate people like top tier companies do, they are a little more recall and study based. Capital One right now has a super broken process that Codesmith alumni are exploiting so try running with it while you can! We've had Codesmith grads be honest about their experience and not pass the recruiter screen for ANY role there, and others who do what Codesmith told them to say who get these interviews... but each person does their own thing. I would just be careful about over-leveling if you have no experience and are interviewed for this role. In the current economy low performers at higher levels who are overpaid go first in layoffs.
