To get their attention talk about what you think you know about the role or ask questions about the role. In the context of; I have heard that geotech in mining involves taking core samples of the rock and then running compression tests to gather the strength of the rock. Then it is modelled using software to determining the stability and structural integrity of either the underground tunnel or open pit wall. Cable bolts and shotcrete is applied to give strength as reinforcing if there is a risk of cave in etc.
Also at Curtin uni we used Slog software to design a raft footing for a house on cohesive soils and also used plaxis to design sheet pile walls to protect a structure from adjacent demolition or earthworks I can't remember. Reiterate that you know this is soil engineering and not rock mechanics which they deal with in mining but you are excited to learn. Less
Relate to the company's core values/mission statement, as well as position duties, and how they could help you develop and mold your skills through different challenges you face. Mention challenges motivate you. Less
Discussed what initially drew me to the subject as a whole, what I did about it, and then what I have become most interested in recently and related that to how I thought Atkins could help me continue learning more about those areas. Less
