    3. Q3. Design a system to push updated packages onto a cluster.

Tips from the candidate

I would do only meta tagged questions if you dont feel confident in leetcode, otherwise majority of prep would be learning on Linux internals and debugging.

Company culture

Non-that many layoffs for PE compared to SWEs. There were 2 kinds of PE

A) You join a team full time

B) You hop between times every few months
