SQL son las siglas de Structured Query Language (lenguaje de consulta estructurado) y un programador SQL es la persona encargada de crear bases de datos SQL y las aplicaciones que funcionan con ellas. Por lo general, utilizan tablas de diseño y recursos de almacenamiento para mayor estabilidad, fiabilidad y rendimiento. En una entrevista para un puesto de programador SQL, pueden hacerte preguntas sobre tus conocimientos de programación y habilidades de resolución de problemas.
Populate an array of numbers from 1 to N (inclusive). Given two numbers, p and q , if a number in the array is divisible by p print OUT, if a number is divisible by q print THINK. If number is divisible by both p and q, print OUTTHINK. Otherwise, print the number.

Suppose there is a rectangular map where you can only travel up or right to go from a start location in the bottom left corner to the top right corner, and each move is discrete. Write a program that prints all possible solutions to get from the start to finish.
How can you efficiently detect whether two linked lists converged? If they do, how do you identify at which node this occurs?
Given sorted arrays of length n and 2n with n elements each, merge first array into second array.
phone numbers: provided a phone number (654-876-0987), return all possible strings that the phone number could represent if 2 -> {A, B, C}, 3 -> {D, E, F}, and so on common substring: find the biggest common substring in 2 strings, "abcdef" "gbcdh" would return "bcd"
Write a function to determine if a bin tree is a valid BST. I wrote a fully working solution in 3-5 minutes. It was also the most optimal but maybe because she needed to kill time, she asked me to rewrite it in what she thought was optimal (her reasoning didn't make much sense). Then she asked me for time and space requirements of the solutions. I said O(n) for both which is correct but she insisted that the space requirement was O(logn) which is wrong.
