LinkedIn SRE onsite coming soon, what to expect ?

Ask recruiter

Anyone here have some suggestions for me please?

When are you interviewing?

All candidates should get the same information from their recruiter. Any further advice in regards to those sections would give you an unfair advantage. Be honest with what you know and don't know and don't Bullshit. The folks interviewing you are SREs. What technical information you know is important but how you approach the problems presented is more important.
