Thales Senior Java Developer interview questions

Last week, I interviewed with Thales for a Software Engineer position. The process consisted of the following stages: Initial Phone Screen (30 minutes) I spoke with a recruiter who asked about my background, skills in Java and cloud platforms, and availability. They also shared more details about the team and projects at Thales. Technical Assessment (1 hour) I completed an online coding assessment that included data structures, algorithms, and object-oriented design problems, mostly in Java. One question involved writing a function to parse log files and identify anomalies. Technical Interview (45 minutes) I met with two engineers who reviewed my code from the assessment and asked follow-up questions. We discussed REST API design, multithreading, and how I would optimize a backend system for performance. Final Interview (1 hour) The last round included a hiring manager and a senior developer. We talked about my experience working on microservices, handling production issues, and my familiarity with CI/CD pipelines. They also evaluated my communication and problem-solving skills.
