First, On-line test. Problems are like count the number of letters in a sentence.etc. Then I got a phone interview. probability question, math problems and coding problems. 1. Find the biggest number in an array without sorting. 2. given 99 numbers from 1 to 100 no-duplicate, find the number that is not there between 1 to 100; given 98 numbers from 1 to 100 no-duplicate, find the two numbers missing between 1 to 100. Then I got an onsite interview. Since I am not CS major, they just ask you given a array, how to find the two biggest number. How to randomize a deck of cards. write a program.
