Bankroll Management Interview Intuition
Bankroll management interview intuition for finite capital, ruin risk, fractional sizing, Kelly links, and expected value limits.
Candidates discussing repeated positive-EV bets and utility.
Finite bankroll changes decisions
A positive expected value game can still be dangerous when bankroll is finite and losses can prevent future play.
Ruin risk
If a sequence of losses can exhaust capital, the probability of ruin becomes part of the decision, not an afterthought.
Concrete example
A toy bet with positive EV but a 40 percent chance of losing the entire bankroll may be rejected under a risk-aware objective.
Fractional sizing
Instead of all-in sizing, repeated-game models often discuss fractional exposure to balance growth and survival.
Kelly link
Kelly-style reasoning is one model for bankroll sizing, but it relies on strong assumptions about probabilities, odds, and repeatability.
Common mistakes
Candidates often stop at positive EV and ignore whether the player can survive variance long enough for the average to matter.
