Technical Support Interviews

Technical Support Interview Questions

"Technical support jobs combine computer know-how with customer service skills in order to help customers troubleshoot computer-related issues. While some employers require candidates to have a bachelor's or associate's degree in computer science, others may only be looking for some level of computer knowledge and an ability to learn as you go. In an interview, expect to answer a variety of troubleshooting questions, such as how you would help a customer with a program that keeps crashing or a computer that won't connect to the internet."

There are two tables: users and countries. Each has two columns. Countries lists a city name and then the country it is in (Moscow : Russia, New York : USA, etc). Users lists an ID and a city name (1 : New York, 2 : Helsinki, etc). Note that there are cities listed in users that do NOT appear in countries. Output a table listing all the IDs and the corresponding countries, but be sure any NULL value is changed to "unknown."
