Candidates report a varied Thales Defense & Security software engineer process: a recruiter or online screen, a technical conversation on C, C++, C# or Java fundamentals and past projects, and sometimes a take-home or HR round.

Candidates describing Thales Defense & Security software engineer interviews mostly point to language fundamentals and detailed project discussion rather than puzzle-style algorithm drilling. Accounts differ, so treat the process as variable.
One candidate who got an offer through a campus drive described an online test on C and C++, operating systems and a coding problem, followed by a technical interview about a project and its tradeoffs, then an HR round. Another, who also received an offer, described a single conversation of about 30 minutes that included a C# class modifiers question. A third candidate, who did not receive an offer, reported a 15-minute recruiter screen, a 45-minute hiring manager round on object-oriented concepts such as abstraction and delegates in C#, REST versus SOAP, and Java versus C# versus C, and then a take-home assignment. That candidate said the take-home was judged on design patterns, algorithm optimization and code quality, not just working output.
So prepare to explain your own projects clearly, including why you chose a design. Review pointers, memory management and OS basics if the role is embedded or low-level, and review OOP and API fundamentals in the language named in the posting. If you get a take-home, write it as production-quality code.
One Senior Software Engineer candidate described Java, Spring, microservices and stream exercises, along with slow follow-up after the interview. Ask the recruiter about next steps and timelines.

Synthesized from candidate reports. Individual experiences may vary.
Candidates report different openings. One described a roughly 15-minute recruiter call on background and fit. Another described a campus-drive online test covering C and C++, operating systems and a coding problem. Expect basics rather than obscure algorithms, though the format may vary by hiring channel.
Candidates report technical conversations of about 30 to 45 minutes. Topics included walking through a past project and its tradeoffs, C# class modifiers, abstraction and delegates, REST versus SOAP, and comparisons of Java, C# and C. Tone was described as friendly and conversational, and the depth may depend on the team and stack.
Some candidates report a final step. One described a take-home assignment judged on design patterns, algorithm optimization and code quality. Another described a relaxed HR round on motivation and fit. Not every candidate reported either step, so confirm the remaining stages with your recruiter.
