Salesforce or Google ?

I am currently working in Salesforce as LMTS, it’s only been 2 months. I am enjoying it here. I recently got an interview call from Google for Staff Software Engineer. I have applied for Australian PR and might get it in 6 months.. Should I continue in Salesforce for now or should I give Google interview and if I get it then Jump.. I don’t want to waste my interview chance and think of it like Il think about it if I clear.. Il only give interview if I decide to join if I get it. please suggest
