FCF, LFCF correct formula?

I've noticed that there some conflicting formulas for FCF (unlevered), which one is correct?

Start with NI: FCF = NI + D&A - change NWC - CapEx

Start with EBIT: FCF = EBIT - taxes + D&A - change NWC - CapEx

These seem to be conflicting because interest is subtracted to get NI, while interest remains in EBIT. I believe that interest(1-t) should be added back to the first formula because interest expense is not to be included in FCF, is this correct?

Then, is Levered FCF = FCF - interest expense?

I am interviewing right now and am confused. Thanks for any help!

in interviews, just use the unlevered free cash flow formula and you're set:

from the top: Revenues - COGS (excl. D&A) = Gross Margin - Operating expenses = EBITDA - D&A = EBIT - EBIT * (1-tax rate) = NOPAT + D&A - CapEx - Increase in NWC = Unlevered Free Cash Flow - Debt Payments (interest, principal) = Levered FCF

Usually in interviews I'll just start at EBIT if they want the formula, but you also want to be able to explain the concepts as well
