Expected portfolio standard for entry level position

That’s really hard to say. Sometimes the company doesn’t have a lot of experience with design or designers and the standards can be surprisingly low. Sometimes they want you to be “rockstars” or “design ninjas” and ask you to be their graphic designer, their logo designer, their website designer and their industrial designer at the same time (better stay away from both of them).

There is a certain industry standard when applying in a design company, but when it comes to corporate jobs in my experience there are no rules. Usually it is more important to be the right person at the right time with the right projects in the portfolio and not an abstract level of “hot sketching”- and “cad monkey”-capabilities.
