Google SRE onsite - tips?

Dear Googlers/ex-Googlers,

I have an onsite in 2 weeks for SRE of the general SWE track (so no networking, no linux internals...etc).

It will be composed of 4 coding + 1 design.

In an effort to set myself up for a success, I wanted to ask you guys for some tips, please.

1) While the recruiter sent me 20~ tabs worth of data, and pretty much the entire list of algorithm/datastructure topics to study for, is there a more narrowed list of “highly likely” topics I can focus more on?

2) Is there any technical competency bar difference between SRE vs SWE on the algorithm/data structure questions?

3) As someone interviewing for SRE should I still prep for Graph, DP, Bitwise, Trees (RedBlack...etc)? These ones seem to be the heavier topics to digest given the time I have to prep.

4) Do 4 coding interviews go from easier to harder or are they all equally hard?
