Qualcomm vs Samsung

Asking for my girlfriend.. My girlfriend joined Qualcomm 2 months ago but was not too happy with the role. She interviewd with Samsung around the same time as Qualcomm but got an offer for them couple of weeks ago. Here are few details Qualcomm: base: 117k Sign on: 15k RSU: 60k over 3 years relo: 8k location: San diego She hasn’t recieved a offer from samung but a verbal one: Samsung: base: 140k sign on: 40k over 3 years bonus: 15% location: San jose 1. Since she has already joined Qualcomm, will she be blacklisted by Qualcomm if she joins Samsung? 2. When i was employed with Qualcomm, the rule was If she decides to join Samsung, i assume she has to give pack the Relocation amount? is this right? anything else that she has to give back. 3. Is Samsung worth the hassle, meaning how is the work culture and oppurtunities, heard all decisions are made in korea and not much scope, is this true?? Both roles are in Modem Systems. Yoe: 5.5 years @Qualcomm @Samsung Edit: Samsung raised her base to 160k Rest is same
