I recently applied at Horizon. Then Alaska opened up …

Obviously anyone who likes money would choose Alaska. But I also need a job. So if horizon job offers me and then a month goes by & i get an AS cjo can i rightfully resind my cjo with horizon. From what I’ve understood its ok. Just cause these are 2 different entities that run their own HR & the info isn’t shared. If you never actually step foot in horizon training; would we be ok?
