if the role focuses on development, understanding deployment pipelines is
highly valuable.
Solve Coding Problems
Spend time each day solving Java coding challenges involving
arrays, strings, linked lists, trees, recursion, dynamic programming, and
concurrency. These problems help improve logical thinking and interview
performance.
Prepare for Behavioral Interviews
Be ready to discuss projects where you solved technical
challenges, improved application performance, mentored junior developers,
handled production incidents, or collaborated with Agile teams. Use clear
examples that demonstrate leadership, communication, and problem-solving
skills.
