Present code together with its context
For a development role abroad, a well-explained project is more useful than a long list of programming languages. Describe the problem, architecture choices, testing and your personal contribution. A public repository or anonymised demonstration can support discussion, provided you respect the rights and confidentiality commitments attached to previous work.
Examine the engineering team’s practices
Ask how code reviews, deployments, documentation and incidents are managed. Communication language, time zones and support for new arrivals affect everyday work. Clarify the contractual work location: an international team or remote-work advertisement does not necessarily permit residence in any country you choose, so geographical flexibility must be confirmed rather than assumed.
