Seagate Technology Platform Developer interview questions

I applied online through some job website and then I was invited for the assessment day. Arrangement was good. Next we were thoroughly informed about the company. Then we were given a technical written test involving topics like linux, data structures, algorithms. OS and C. We were not told about the language or kind of test. They even invited people from no background of computers or programming. They were pretty much angry about it. Next was interview, but I didn't face it as i failed in assessment test.
