How to Prepare for a Python Interview After a 6-Month Coding Break

Developers returning to Python after a six-month break face a specific challenge: core concepts remain intact, but syntax recall and confidence have diminished. A structured 21-day preparation plan recommends against immediately grinding hard LeetCode problems, as this often leads to frustration while leaving fundamental gaps unaddressed. The guide prioritizes refreshing key intermediate topics such as mutability, scope resolution, default mutable arguments, and generators during the first two weeks. Algorithm practice and mock interviews are introduced gradually in the second half of the plan, with emphasis on pattern recognition and thinking out loud. The approach is designed for developers with an interview two to four weeks away who need targeted revision rather than a full relearn.
