Show enthusiasm for contributing to meaningful projects that impact communities.

Be Ready for Technical Challenges

While the interview may include discussions about your background and experiences, be prepared for technical questions or challenges that assess your problem-solving skills. You might be asked to explain your thought process in tackling a specific technical problem or to walk through a coding challenge. Practice articulating your approach to problem-solving, as this will demonstrate your analytical skills and technical competence.

Ask Insightful Questions

At the end of the interview, you will likely have the opportunity to ask questions. Use this time to inquire about the team dynamics, project management methodologies, and how success is measured within the role. Asking thoughtful questions not only shows your interest in the position but also helps you gauge if HNTB is the right fit for you.

This is a chance to reiterate your interest in the position and briefly mention a key point from the interview that resonated with you. A thoughtful follow-up can leave a positive impression and keep you top of mind as they make their decision.
