710,358 programador sql interview questions shared by candidates

The written exam was of 1 hour and included the following questions: (1) Write a function that will receive a string as an input and will return the string in reverse order. (2) Write a function that will print the following series of numbers using only one loop: "1,2,3,4,5,6,7,8,9,10,9,8,7,6,5,4,3,2,1" (3) Write a function that will print all the multiples of 3 between 1-200 ( in reverse order ) There were other programming questions as well but of the same difficulty level. Along with the coding questions there were some analytical and QA questions as well. And for me the best part of this exam was there's no language specification. You can answer all the coding questions in whichever programming language you are comfortable with. So, after giving the exam I was impressed to know that they basically want to see how much problem solving skills do you have rather than evaluating you by the number of languages and frameworks you know.
