Pretty straightforward. I interviewed for the PE University Grad role. The first round was mainly a basic coding round and a PE basics round. Once I passed that, there was a loop of 3 interviews - System round (focussed on OS concepts), another coding round and a behavioral round.

I had two screening rounds and 3 interview loop rounds, Meta leetcode questions, systems design can be extensive. Questions can be repeated so look out for all the available questions online. Systems debugging is a very important topic

Recuriter round then technical screen with an engineer that then final stage which is four rounds, 2 coding 1 system design and one behavioural, for Production Engineer the questions are often a mix of LC questions and practical file system operations
