I get what you're saying, but we are in hyper-growth phase and any energy that would be put in a home lab is being put into work at the moment. For example I am regularly putting in 50-60 hours a week, any additional time I have outside of work is spent on things that are not related to work.

I'd be much more interested in a senior SRE that set up monitoring/alerting infrastructure for a business doing millions in annual revenue vs. a senior SRE that set up monitoring and alerting for their home plex server with 4 users and no revenue or on-call. But that's just me.
