The interview process is not very clear. It is probably to understand your writing skills and communication skills.
In a nutshell, what this position does is to help companies apply for projects and obtain government financial support. Therefore, if you want to apply for a project, you need to prepare an application report, feasibility study report and other materials (if you edit it yourself, you must also know the project economic analysis). At the same time, you have to help the company strive for more honors (those that are good for declaration (patents, high-tech enterprises, technology novelty searches, key new products, etc.)). The complete process of a project also includes communicating with the government and letting the government work according to your requirements. Application materials and other documents such as energy assessment, environmental assessment, project filing, etc. After the project is declared, you still have to track the project, and it will need to be inspected and accepted at that time. If the inspection fails, it will not be of any benefit to the company. In short, it is not complicated at all. It has only one goal, which is to obtain financial support from the state and expand many things around this.
Hope it is helpful to you.
