1hr phone interview: - Tell me about a time you helped a struggling team member. - Tell me about a time you had to learn something new - given a string find the first unique character (non-repeating character) - given a binary tree return true/false if it is BST 3hr interview: - more "tell me about a time..." questions - given two words return true/false if they are anagrams of each other - merge two sorted lists and remove duplicates
Amazon leadership principles, lots of little considered questions that is not related to positions. Medium programming questions from leetcode. OOP question And regular expression questions that is not very good explained.
Amazon Prime Air is developing a system that divides shipping routes using flight optimization routing systems to a cluster of aircraft that can fulfill these routes. Each shipping route is identified by a unique integer identifier, requires a fixed non-zero amount of travel distance between airports, and is defined to be either a forward shipping route or a return shipping route. Identifiers are guaranteed to be unique within their route type, but not across route types. Each aircraft should be assigned two shipping routes at once: one forward route and one return route. Due to the complex scheduling of flight plans, all aircraft have a fixed maximum operating travel distance, and cannot be scheduled to fly a shipping route that requires more travel distance than the prescribed maximum operating travel distance. The goal of the system is to optimize the total operating travel distance of a given aircraft. A forward/return shipping route pair is considered to be "optimal" if there does not exist another pair that has a higher operating travel distance than this pair, and also has a total less than or equal to the maximum operating travel distance of the aircraft. For example, if the aircraft has a maximum operating travel distance of 3000 miles, a forward/return shipping route pair using a total of 2900 miles would be optimal if there Each aircraft should be assigned two shipping routes at once: one forward route and one return route. Due to the complex scheduling of flight plans, all aircraft have a fixed maximum operating travel distance, and cannot be scheduled to fly a shipping route that requires more travel distance than the prescribed maximum operating travel distance. The goal of The system is to optimize the total operating travel distance of a given aircraft. A forward/return shipping route pair is considered to be "optimal" if there does not exist another pair that has a higher operating travel distance than this pair, and also has a total less than or equal to the maximum operating travel distance of the aircraft. SARRA: For example, if the aircraft has a maximum operating travel distance of 3000 miles, a forward/return shipping route pair using a total of 2900 miles would be optimal if there does not exist a pair that uses a total operating travel distance of 3000 miles, but would not be considered optimal if such a pair did exist. Your task is to write an algorithm to optimize the sets of forward/return shipping route pairs that allow the aircraft to be optimally utilized, given a list of forward shipping routes and a list of return shipping routes. Input The input to the function/method consists of three arguments: Input The input to the function/method consists of three arguments: • maxTravelDist, an integer representing the maximum operating travel distance of the given aircraft; forwardRouteList, a list of pairs of integers where the first integer represents the unique identifier of a forward shipping route and the second integer represents the amount of travel distance required by this shipping route; • returnRouteList, a list of pairs of integers where the first integer represents the unique identifier of a return shipping route and the second integer represents the amount of travel distance required by this shipping route. Output Return a list of pairs of integers representing the pairs of IDs of forward and return shipping routes that optimally utilize the given aircraft. If no route is possible, return a list with empty pair. Examples Output Return a list of pairs of integers representing the pairs of IDs of forward and return shipping routes that optimally utilize the given aircraft. If no route is possible, return a list with empty pair. Examples Example 1: Input: maxTravelDist = 7000 forwardRouteList = [[1,2000),(2,4000],[3,6000]] returnRouteList = [[1,2000] *** Output: [[2.11] Explanation: There are only three combinations, [1,1],[2.1], and (3,1), which have a total of 4000, 6000, and 8000 miles, respectively. Since 6000 is the largest use that does not exceed 7000, 12.1) is the only optimal pair. LL2,1]] Explanation: There are only three combinations, [1,1], [2,1), and (3,1), which have a total of 4000, 6000, and 8000 miles, respectively. Since 6000 is the largest use that does not exceed 7000, [2.1] is the only optimal pair. Example 2: Input: maxTravelDist = 10000 forward RouteList = [[1,3000), (2, 5000), (3, 7000], [4, 10000]] returnRouteList = [[1,2000], [2, 3000], [3, 4000], [4, 5000]] ******: Output: [[2, 4]. [3,2]] Explanation: There are two pairs of forward and return shipping routes possible that optimally utilizes the given aircraft. Shipping Route ID#2 from the forwardShipping RouteList requires 5000 miles travelled, and Shipping Route ID#4 from returnShippingRouteList also requires 5000 miles travelled. Combined, they add up to 10000 miles travelled. Similarly, Shipping Route ID#3 from forwardShippingRouteList requires 7000 miles is the only optimal pair. Example
(Phone Interview) What is the difference between a class and an object
I was asked problem based questions where the interviewers presented/described to me, a scenario and asked questions based on that. Personally I enjoyed the questions as they made me really think, and when I was stuck a few times they did give me a nudge which was good.
Given 2 parallel CPU of 1 GHz and one single CPU of 2 GHz, what is the difference between them?
Asked my about my masters project.
Mainly architecture related questions ( CPU/GPU/pipeline/SIMD etc ).
