The interview lasted for one hour. There were two interviewer. They first asked me for 30 minutes about what projects I have worked on and what my research is about. For the rest of 30 minutes, two technical questions were asked. 1. Given a number of double type "a" and an integer "b", write a function "pow(a,b)" that returns the value "a" raised to the power of "b". They will ask you to improve the efficiency if your code runs slower than O(b log b). 2. Implement an interface in which the first method "store(int val)" stores "val" in the data structure you chose to use and the other method "twosum(int value)" returns true if and only if two numbers stored in the data structure add up to "value". They will ask you to improve the efficiency if your code runs slower than O(n), where "n" is the number of numbers stored in the data structure.
