My friend, lately had interesting experience of taking Production Engineer at Meta interview.
The interview type is Linux Troubleshooting. First time he had such interview, and it was quite interesting.
In short:
There is deployed web app (frontend, backend and database) on the single machine, single datacenter. There is alert that checks http status code by curl the host.
At 2:06 AM you are getting called by alert that server is down. You have root access to the machine.
Your task: trouble shoot the issue, find root cause, mitigate and suggest preventative actions.
The interview process is: you are telling what you gonna do, then you tell the exact command to interviewer and interviewer is telling you what this command shows you.
Friend passed the interview with slight help of interviewer

Next stream - we can go through the question, and try to solve it together. Might be interesting experience

It is funny, how 4 years ago I spent couple days on the 1 dp
problem and was not able to solve, but now, literally a matter of 5-10 mins in python.
This is literally just a matter of practice and pattern recognision, not that much of intelligence, if we are talking about easy/mid leetcode

I tried startups, and this is why I don't want to work on startups at all.
Only if there is big equity chunk - then it makes sense - otherwise - never.
Yeah, software engineering primarily needed to solve business problems, and stuff, but it is disgusting from dev exp. In early stages, if CEO/CTO is wise person - he/she will always push for results, not good code and practices. It means devs gonna poke around in shit until you become big enough when good eng practices make sense for reputation, stability, availability, etc
The other side of the coin is too old projects, when you are unable to change stuff, because it will break.
So IMO - the best project for dev experience is mature project, not "NEW", not "legacy", or your own side project that you do NOT for money.

Found very nice thing for recalling the approaches to problems and "patterns" kind of.
