Amazon Software Developer interview questions

I had 3 telephone interviews before I got a reject. All 3 were technical as expected. Interviews covered almost all parts of software development-- OOD, Design Patterns questions, OS conxcepts, DB concepts. Be confident and do not bluff( its like digging your own grave). Be thourough with OOD. Scripting language knowledge very helpful. Also if you have worked in Linux then it is helpful.

The interview is consistent of 3 rounds, the first round is HR interview. The second round is technical interview.During the technical interview, you need to write some code to demonstate your skills. The last round is interview with one manager, you need to answer many question.
