Tell me about a time when you had to receive negative feedback. There are 4 chairs in a circle. You flip a die, if it lands on 4, you move counter-clockwise one seat. If it lands on any other number, you move clockwise the number of seats you got on the die. What is the probability after 6 die rolls that you end up on the same seat you started in?

youre blindfolded and have 26 coins on table in front of you, 16 tails, 10 heads (facing up). make two piles so that each pile has same amount of heads. Theres no discerning the difference between heads and tails and you have to use all the coins to make your two piles.
If today is Friday July 8 2022, what day of the week will it be on July 8th 2032.
A has 6 points and B has 4 points. The flip a coin and if it's a head, then A gets a point. If it's a tail, then B gets a point. What's the probability that A wins with 10 points?
How many coins would you have to toss such that the probability of getting two heads in total is 50%? If A, B, and C are integers between 1 and 10 (inclusive), how many different combinations of A, B, and C exist such that A<B<C? Consider a set containing the integers between 1 and 10 (inclusive). How many unique subsets exist such that the sum of the elements of the subset is 10? What is the expected number of consecutive heads in a sequence of 3 coin tosses?
Home assignment: OANDA operates a trading platform which allows clients to buy and sell currency pairs. When a client makes a trade to buy or a sell a currency pair, the company must decide to either (a) offset the exposure immediately by hedging the trade with a bank, or (b) hold the exposure for a period of time allowing the market to move before hedging the trade. If the company hedges the trade immediately, they will realize a small profit for each trade. If they hold the exposure, then they may realize a large profit or loss, depending if the market moves with or against the exposure. You are tasked with determining (for each client trade) whether we should hedge the trade immediately or should hold on to the exposure for a period of time. Describe how you would perform this analysis, including what data, tools, or processes you would use. State your assumptions. Comment from HR: The trading team is not looking for an exact solution, more to see your understanding of the problem, and for a proposal about how one would go about finding a solution to the problem. No formulas are required.
