This is a terrible and unfair practice.

Going through one telephone interview is fine.

However, there are 4-5 people in the on-site interview.

Most of them appear to be young graduates. One older person also asked the same logic question.

I don't know how much they truly understand about storage area networking technology.

They use an unpractical algorithm to test candidates.

This algorithm tests a ridiculous single linked list that points back to a certain node. You have to solve it the way they expect; you cannot add any fields inside the structure. If you don't provide the answer they want, they say, "It's a very basic problem."

This is a bunch of humiliation toward candidates, even though I am humble to face them. This is very unprofessional. I don't know how the U.S. will ready this group of H1 [visa holders] to be U.S. citizens.
