This is yet another question asking you to compare and contrast two technical terms. During a back end developer job interview, interviewers will ask you technical, operational, behavioral, and general questions. While they often start with general questions and sometimes end with behavioral questions, they can use all these types of questions throughout the interview. No two interviewers are alike, so you cannot anticipate the types of questions you will be asked and when they will be asked. The best way to perform well during an interview is to carefully listen to the question, provide the interviewer with an answer in clear and easy-to-understand language, and be prepared for follow-up questions used to explore the topic in more detail.

"Both JOIN and UNION are technologies associated with SQL operations and multiple data sets. JOIN allows users to lookup or query records on two tables based on the specified conditions between the tables. UNION is an operation that combines two similar data sets to generate a resulting data set that contains all the data from the original data sets. Union does not require any specified conditions for joining the data sets."
