The person who sends the recruitment information doesn't know what the position is mainly responsible for.
This position is responsible for all kinds of things, and then can't find the focus, that is, chaos, and directly write computer-related work.
This position is highly confidential and it is not convenient to disclose too many details of the work, but I think this possibility is very small. Confidential posts will not be written like this easily. I met a friend who recommended me to work in a confidential unit before. This is not a process.
Is it a training institution? Check their company name directly, and then go to their website to find out, or the industrial and commercial bureau can directly check what their main business is, and you will know. I hope the analysis I gave you in my own time can help you.
