Divide array of numbers from 1 to 100 into 2 groups which have the same sum.
You must pass the online test before moving on to the next step. It is not extremely difficult, but you have to possess good knowledge of probabablity, statistics, & quantitative. You have 1 to 15 minutes to answer a question depending on the difficulty, thus you must be able to solve the probably immediately, no time to research online. Given the time constraint, the difficult part is that you MUST use math on a regular basis & remember which formulas to use. That was my problem, haven't used these tools for quite some time. I was pretty good at Math (top 1% for SAT & GRE), but I didn't pass the online test :-( The interview could have been more well-rounded by giving the candidates more chance to present their capabilities beyond the online test result.
What is the complexity of the Quick Sort algorithm?
You have n coins and one of them is bad (either heavier or lighter), what is the maximum number n can be if you need to determine the bad coin in 3 weightings of a scale.
There are four balls, two black and two white. You pick two and random and flip their color from one to the other and repeat. How many times would you do this to ensure all four balls are the same color?
Bag with 4 marbles. Two red and two blue. Draw the balls one at a time, but before it comes out, try to predict the color. If correct, you get a dollar. If you play optimally, what is the expected value of the game?
Is now a good time?
Given an unfair coin that is heads 2/3 of the time and tails 1/3 of the time, how do simulate a fair coin?
probability questions like “You’re given a biased coin with a known probability 𝑝 of landing heads. How would you determine the expected number of flips until it shows heads twice in a row?”
