I have been doing software programming, dev, BI reports using SQL and now QA automation testing in selenium and other nodejs tools, etc for over 15 yrs. I work in a scrum agile environment now, doing QA testing on google/ waze maps testing, transportation maps and web based application. I am a scrum master certified but not doing that, but as a QA in dev team. I am thinking of taking the CQA certifcation. Would that be a good area or relevant. I was thinking of the CQE but think it might be too tough like the istqb. suggestions? I am not sure sometimes how much more can that really help..
