How does a developer manage to switch to a domain or industry completely outside their experience?
Right now dropshipping is a new skill you can switch by learning its softwares. See this to learn few of them - https://www.howtobuysaas.com/blog/software-for-dropshipping/
So this was a case of the demand for a tech skill outwaying the supply and therefore the banks didn't get to be too choosey.
So perhaps one way to switch would be to learn a tech skill and use that as leverage. i.e. Rust to get into blokchain/crypto.
Julia to get into Bigdata, AI and ML.
Kubernetes to get into DevOps/CI-CD etc.
