Getting to interviews without a car in Boston after 16 years as a payroll clerk

I do not have a car and interviews in Boston are spread around. I do not usually post, so bear with me. Some employers are off the main lines. Any rideshare programmes?

Our transit agency has a reduced-fare pass for people with low income. The application took a week.

If you can, schedule interviews back to back in the same area to save fares.
