Testing Interview Questions

Testing interview questions are an essential and unavoidable part of beginning a career in software development. Software testing is the process of finding bugs in a program or application. This is to ensure that the product being developed works as intended for the consumer. If you're going to be interviewed for a software testing position, be prepared for a rigorous screening process.
