1. How would you build Amazon?
2. Winter is coming! Your first job during the contest is to design a standard heater. Now, you are given positions of houses and heaters on a horizontal line, find the minimum radius of heaters so that all houses could be covered by those heaters. So, your input will be the positions of houses and heaters seperately, and your expected output will be the minimum radius standard heaters should provide.
3. Given an array of integers, find all unique quadruplets [a, b, c, d] such that a + b + c + d is equal to a given target. Note that the quadruplets must be in non-descending order (i.e., a ≤ b ≤ c ≤ d) and the solution set must not contain duplicate quadruplets.
4. What are some behavioral questions to test for culture fit?
5. Explain your project in detail, including the high-level design (HLD), low-level design (LLD), and schema you created using draw.io.
