I spent five years on mine. Doesn't come up in interviews. If I had to explain, it was working and school, same time. I've got extra credits to show, three classes, almost one extra semester. Cannot remember, last employer to pull transcripts, if any
Was thinking today, related to something else, but can apply here. No excuses, just state facts. No need to explain six years, my uncle took six years, can be generalized assumption of working your way through school. Just let it stand, it did take you, six years, but you have it. .
Hope all goes well
