The interview process included a telephonic round, followed by three technical face-to-face rounds and a telephonic discussion with the hiring manager and HR.

The telephonic round was a screening round covering the basics of Java, JavaScript, and SQL.

The first technical round included questions on problem-solving skills, the number of approaches to solve problems, solution optimization, and details of the Java language.

The second technical round focused entirely on data structures.

The third round covered details of past projects, your understanding of all technologies mentioned on your resume, and a coding problem.

Write the code for a problem and write as many unit test cases as possible.
