It&amp;#x27;s absurd that anyone that can talk about this stuff at a basic level is seen as some sort of ultra-skilled professional.

It’s extremely telling that when you spend time in tech forums most people dread system design questions as the harder side of interviewing for senior level SWE roles…&lt;p&gt;I think this is a bit unfair, the software industry is so big now there are lots of different sub-sectors. Big Tech companies have huge scale problems that are kind of unique. Most developers work on products that only have a few hundred users at a time.&lt;p&gt;Your 20 years experience is a bit telling. I&amp;#x27;m the same age, back then SWEs usually had full access to production environments. Now everything is segregated and devs can&amp;#x27;t experiment in prod and end up getting detached.</text><parent_chain><item><author>tristor</author><text>Honestly, the bigger issue is that most SWEs just aren’t very good.
