Cons
Your career is tied to how well your manager likes you. if he packs and leaves, will be hard to advance biggest downside is that HR isn't honest about important topics when relocating and offer zero assistance to acclimate for dependents. They also tell you that they don't offer full or half expat packages, only voluntary expats at AVP level which is not true another big downside is their tech stack. They hire a bunch of incompetent cheap indian labor at support which means if you are a developer or business analyst, you will bang your head against the wall alot indian managers in tech hire indians, despite if candidate is competent or not and have no problem spending thousands sponsoring green cards, it's pretty bad
