517 java backend developer interview questions shared by candidates

Hiring Manager Interview: The interview focused largely on soft skills and engineering practices, including topics such as the difference between an engineer and a developer, giving and receiving feedback, testing strategies (e.g., the test pyramid), and approaches to code reviews. Coding Challenge: The experience during the coding challenge varied significantly depending on the interviewer (mine was absolutely terrible). The discussion covered topics such as the Dockerfile, dependency/version choices in the pom.xml, log and debug console output, and design decisions. In some cases, I was also questioned about features that were not part of the original challenge requirements.
