I understood it.
You can get some idea about what you are doing is good or not by analysing market trends and JDs.
But sometimes some trends are just a bubble.
Being a test automation engineer, I have a very high level idea about what's in demand or will be in demand and what is considered good work for growth.
But if someone from testing, test automation background would have asked this question, I could have asked to share more details about the current work to give insights.
So similarly if you find a genuine mentor/senior to understand what you are doing, what are your aspirations and how you can bridge the gap.
That would be the best strategy IMO.
