Where are links to the NIS job vacancies?

Once the NIS career portal is created im guessing the next step is to find a job vacancy to apply for. I haven't found one yet does anyone have the links to the vacancies?
Good afternoon! Where do you usually look for job offers? I am trying to find a reliable company, but it seems like now it is very complicated. There are a lot of online jobs that suit me, but I am not sure I will pass the interview. Now I am preparing for that. I use these questions. Do you think they are popular?
