Defect tracking is one of the important topic in manual testing process because any testing process will results in some or more defects and the testers will assign the defects to developers and then developers will fix the defect and re assign the defect to tester who has originally created it, and tester will re-test it and if it is pass the he will close the defect or else he will assign it back to developer who fixed.
The entire process is done using a tool called defect tracking tools and I am familiar with HP's quality center , IBM's clear quest. This is a must manual testing interview questions.
