It took me nearly 7 years to finish my BS degree in CS. I took a couple of years off in the middle and then at the end I was working full time and taking part time classes.

I also took 7 years to finish my Master degree. I was working full time and only took a couple classes a year. I also took off a few semesters off when I had kids.

Nobody has ever asked about either situation. I wouldn't worry too much. As a hiring manager I've never cared about that.
