Answer HR motivation and project experience questions

You are interviewing for a technical role (e.g., software engineer, data scientist, or research engineer) at a tech company. In an HR screen, the recruiter asks several behavioral and motivation questions:

1. Why do you want to join our company?
2. What is the project you are most proud of?
3. Tell me about one of your recent projects.
4. When did you last read a research paper, and what was it about?

Prepare structured, concise, and compelling answers to these questions that would make sense to a non-technical HR interviewer while still showcasing your technical depth and impact.
