Upcoming recruiter call Google

Hi everyone, As the title says I have an upcoming recruiter call with Google for SWE role. The recruiter contacted me so I don’t have any job description and am just looking for tips what should I expect in this call. Based on reading some Reddit posts: I should prepare to talk about my resume, projects and maybe salary questions. 1. Can I ask 6 weeks time to prepare? Or is it too much? The recruiter did mention he is hiring for Q2/Q3. What is the acceptable range to ask? 2. What should I say for salary? I also don’t know the level as I don’t have any job description but I am assuming it is L3. Should I say total compensation or just base based on levels.fyi? 3. Any other helpful tip would be most welcome. It is my first time interviewing with Google so don’t want to screw it up. Please be kind :)
