Amazon Software Developer - Internship interview questions

There will be 2 phone interviews of 45 minutes each. Most probably they will be technical interviews in the scope of algorithms and data structures

i was contacted by a recruiter told me that they would set full time interview for me but i was not graduating back then, so then changed it to internship interviews. There should be two 45 minutes phone interviews. But that was a mess, these two were set in two different days and one of the interviewer didn't call! And they set another one, turned out the recruiter mixed time. That was totally a mess. And recruiter didn't contact me for several weeks, when i emailed her asked about how's it going she just replied a rejection letter. Awful experience.
