The interview process consists of three rounds. The first round takes place in Wan Chai with three managers, focusing on assessing technical skills, experience, and role fit without HR involvement. The second round occurs at the Tsing Yi Oil Depot, where managers evaluate operational knowledge and site-specific challenges, again without HR presence. The final round involves the HR team and a director, emphasizing cultural fit, alignment with company values, and strategic goals. This "hush round" suggests a confidential discussion, possibly involving final negotiations. Candidates should prepare thoroughly, understanding the company's operations and values, and be ready to discuss their contributions and alignment with the company's vision.
