Crypto Perpetual Futures Interview Guide

Crypto perpetual futures interview guide covering perpetual contracts, mark prices, funding, leverage, liquidation, basis, and risks.

Candidates discussing digital-asset derivatives and market-neutral trade mechanics.

Perpetuals avoid fixed expiry

A perpetual futures contract is designed to track an underlying market without a standard expiry. Funding and mark-price mechanics help link contract value to spot value.

Funding connects longs and shorts

Funding payments can transfer value between long and short positions depending on contract premium or discount. The exact mechanism is venue-specific.

Concrete example

A long spot and short perpetual position may appear market-neutral, but funding, fees, basis movement, borrow, margin, and liquidation rules still matter.

Leverage changes risk sharply

Perpetuals often involve margin and liquidation risk. Even a hedged position can fail if collateral, venue, or price-path assumptions break.

Common mistakes

Candidates often describe collecting funding as free money. Strong answers treat funding as one component of a risky derivatives and financing trade.
