Google onsite Hyderabad vs Bangalore

Ok I know Google onsite interview bar is same across the world and people dont tend to Bias much.

But from my personal experience a lot of my friends have been rejected at Hyderabad office as comapred to Bangalore. Is it true that Bangalore office interviews are realtively easy?

Also my interview is for Europe/London office so should I instead travel to London for interviews.

P.S. I have no interest in travelling Europe just want to maximize my odds.

Yoe: 3
LC: 300 questions
level: L3

Additionaly my recruiter is kind of pushing for 1 system design too. Im pretty good at Algo DS, should I take the system Design?
