Economically similar to a forward, with one important mechanical difference: daily margining.
Consequences: almost no counterparty credit risk; a small pricing difference from forwards when interest rates are correlated with the asset price, because the timing of cash flows matters; and a live operational concern, since you can be directionally right and still face margin calls that force liquidation.
For interview purposes: "essentially the same price, but daily settlement creates a convexity adjustment when rates and price are correlated" is complete.
