Amazon Developer interview questions

Had a phone interview after submitting resume through College. Questions were basically on writing code and speaking it aloud - questions were based on given an array of odd numbers and one even number, how would you identify the even number, diff between hash tables and linked lists etc

Had 3 phone screenings, process took some time due to my personal activities and business, everyone from amazon was quite nice and helpful, there was no problem to reschedule date/time with HR questions were challenging but expectable, you need to know a lot from various areas like java networking databases algorithms oo design
