In first round, they asked math questions in 30 mins. One is probability problem. Second is geometrical sequence. Third one is to figure out the number if given the sequence recursion formula. For the onsite review, they asked your background very harshly and tried to criticize your job. Then I was required to do another math problem.
Giving a recursive equation and calculate the normal expression.
Figure out fastest way to cross all the people from one side of the bridge to the other with some restrictions
If you flip an unfair coin x times, the odds of getting three heads is y. What is the probability of getting heads after flipping the coin once?
Simple math problems on geometry and probability
Q1: A and B are flipping a coin. A flips first, then B. What is the probability of A winning first? Q2: What is the volume of a cube inscribed in a sphere with radius = 1? Q3: There are 25 horses, each of which runs at a constant speed that is different from the other horses. Since the track only has 5 lanes, each race can have at most 5 horses. If you need to find the 3 fastest horses, what is the minimum number of races needed to identify them?
