I applied in-person. The process took 2 months. I interviewed at Amazon (Chennai) in Feb 2011
Interview
Not difficult, they just want to test your english language skill and confidence. There would be MS-Excel knowledge test. It wasnt difficult either. Your 1 on 1 with the manager is important, impress them there, dont be snobbish tough.
I applied through an employee referral. I interviewed at Amazon (Chennai) in Jul 2015
Interview
The HR had sent a mail inviting to attend the interview. The mail only had details about job description and interview time and venue. After reaching and before starting the interview process they disclose that they are hiring only for night shifts.
They should enclose all details about the position including the time and pay in the mail itself so that only those interested will attend. Otherwise it becomes a waste of time for all.
I applied through an employee referral. The process took 2 weeks. I interviewed at Amazon (Bengaluru) in Jan 2015
Interview
Good hiring process. The pace was very fast. Started the interview with aptitude test followed by a face to face. Friendly people and they make you feel comfortable. If they find the right and suitable candidate the total face to face interview process will last a maximum of 15 mins.
