Beyond technical proficiency, they want to see that you understand best practices, can discuss tradeoffs between different approaches, and stay current with industry developments.

Be honest about your experience level while showing enthusiasm for learning and contributing. Prepare thoughtful questions that show you've researched the company and role.

Will I face algorithm questions?

Possibly. Junior roles often include basic data structure and algorithm questions. Practice arrays, strings, and simple problem-solving.

Connect your background to the role requirements, emphasizing transferable skills where direct experience is limited. Practice explaining your career journey and motivations clearly and concisely. In Junior Backend Developer interviews, demonstrating both technical depth and clear communication is essential.
