First off, it’s hard to get non-technical jobs at a tech startups. I’m just basing that off of my experience trying to get testing jobs at tech companies.
Software testing is technical but you don’t see job openings for it until the company has at least 20 people. It can be pretty challenging.
It feels like in the early days of a tech startup, most of the open position are technology focused. You’ll see positions for programmers, engineers, data scientists, developer operations, things like that.
There just aren’t a lot of non-technical jobs available. So through basic supply and demand you can see why the jobs are always difficult to get into.
