Amazon Data Engineer I interview questions

Extremely disappointed with the over process and the approach of the interviewers. This was the second time in 4 years I had applied and hoped for a better experience but unfortunately no. *************** The first time I was repeatedly interrupted while answering questions and i felt a bit of an ego issue where the interviewer was only willing to hear what his approach of a solution was and there was no update whatsoever after that , not even an email stating I was rejected. ************** **************************** This time I though It might be better but it wasn't. Its a surprise a company as big as amazon can not have a defined recruitment process , I was approached by a recruiter online and was asked if I was interested in applying for a few open roles. I was and I went ahead by sharing my profile. No one explained what the process would be , I was asked to respond to a small questionnaire and then got an email for a technical discussion . the person taking the interview had no idea what position I was applying for , neither he knew if I had done the questionnaire. After this discussion I was told that I would be getting another call for a technical discussion. This time the interviewer asked a few SQL questions but was not willing to take answers rather kept saying , can you solve it by a different way.Anyway this was done and then I get an email that I there would be 3rd technical discussion. Again this time as well the interviewer had no idea what position or department i was being interviewed for and asked a few SQL questions that I answered. A few days later got an email that they are considering other for the role. Although I was disappointed by being rejected , I was more pissed off with the entire process where i feel amazon team is just going through the interview process without knowing what they need and how to evaluate people. ***************************
