Interview
In total, there were three rounds of face-to-face (in-person) interviews. The first two rounds were with different members of the team, where I had the opportunity to discuss my skills, experience, and how I could contribute to their projects. The final round was with the hiring manager, which involved a more in-depth conversation about team dynamics, expectations, and long-term goals within the role.
