Unix/Linux scripting questions. Lots of SQL Questions 12 Amazon Principles questions Just study basic Linux commands. Make sure you understand SQL well. Like join types, indexing, etc. Make sure you have a story for every leadership principle. These examples aren't from my interview. Google the questions and you can find lists of several possible questions. Examples: Tell the story of the last time you had to apologize to someone. Who was your most difficult customer? Tell me about a time when you had to leave a task unfinished.

Written Test: Contains 15 MCQ and 2 programming questions. Programming Question 1: Find the username from given mail. (E.g: abcd@gmail.com, here the word before @ is username . So we have to print abcd) Programming Question 2: Calculate sum of diagonal of given unsquare matrix E.g: For matrix [[1,2,3],[4,5,6]] output is 6 and for matrix [[1,2],[3,4],[5,6]] output is 5. Round 2: Technical Round 1 Programming question 1: Sum of pair of numbers from given array which is equivalent to given value : (For E.g: array ( 1,2,3,4,5,6) and value is 6 . so, output is (1,5) gives 6 and (2,4) gives 6. They have checked all the corner cases and also they are checking space and time complexity. Objective question 1: In a excel, columns are named as A,B,C,...,Z,AA,AB,AC,....,AZ,BA,BB,BC,....,BZ,........ The task is we have to map numbers for that columns . E.g: A is 1 , B is 2 ,.... Z is 26, AA is 27, AB is 28, AC is 29 ,.... AZ is 52 , BA is 53 ...... We have to find the equivalent number for the given column name For E.g: for this AB is equal to 28 and ABA is 729 . We have to derive mathematical formula for it. Round 2: Technical round 2 1. check whether the word Amazon present in given file. 2. given two file with name and marks. Print the total mark for the person file 1: abc,70 def,90 ghi,100 file2: def, 75 abc, 90 Output: abc,160 def,165 ghi,100 3.Print the name of file which has volume of more than 1 GB from a directory 4. Print the 5th word of line which is divided by 3 ( printing 5 th word from line number 3,6,9,12,.....) 5. Check given two string is rotated string . (E.g : string1= ABCD , string2= BCDA. rotating string1 by 1 position will give string2. So print Yes) 6.Trouble shooting question.For E.g : Consider the application Facebook , which supports both mobile app and web app. Problem is a person is uploaded a photo in web app . But the photo is not visible in Mobile App. How did you analyze and find the root cause. I have listed the some steps . And interviewer asked what next ? he asked what next until he get all possible ways Round 3: Managerial Round 1: Questions are about Amazon Leadership principle and project related questions Round 4: Manager Round 2: This also should be Leadership principal . But interviewer asked Technical questions. 1. Gave a program using Stack Datastructure and find the output of it. 2. Shell script . Download a zip file from given website . Upload it to remote server and extract the zip file in remote server. Ensure the file permission and also count the number of file which has extension as *.html and *.css 3.Some project experiences
