Hunter sales and co

Hi, I've recently been offered an interview with Hunter's sales and co (insta: @huntersalesandco) for an entry level marketing opportunity. Has anyone experience with them, cause their Instagram looks kinda scamy? Always introducing new staff whose life has been transformed through this job. They don't say what they market and it all looks a bit fishy. Any help would be appreciated!

edit: thanks for the great respond and help, I would encourage to leave feedback on Google review to highlight their dodgey business practice and to safe fellow job seekers time and effort.
