Received an email from HR about scheduling a phone interview. I applied at their website before that but they also could have found my resume another way. First phone interview was all techincal and asked me to code a method to do a depth first search of a binary tree. And also had me do a coding problem where I had an endless stream of integers and I had to keep track of the 1000 largest in big O of log N time. Second phone interview was all technical and had be right a method to take in two numbers and raise one number to the power of the other ex: 2^3 = 8; Next questions was given an array of numbers to remove the duplicates in big O n log N times with memory space of big O(1). I didn't make it pasted the second phone interview
