Amazon Software Engineer Test I interview questions

Had three phone interviews in total but did not make it to the onsite interview. I found the amazon recruiting process very confusing as i was contacted by three different recruiters at different times, all of who did not have knowledge that I had already previously been contacted by another recruiter. The interviews were pretty standard, data structures, inheritance, design, polymorphism.

I am in Dev but interviewed for SDET, The thing which i did not answer correctly are Test questions.
