I applied through an employee referral. The process took 2 days. I interviewed at Austin Lane Technologies (Denton, TX) in Sept 2017
Interview
Three interviews. Two talking to people. One for a written test. Not much other than that. The written tests are a bit silly. Make sure you memorize binary search. You can probably just guess on the support test and still pass.
Interview questions [1]
Question 1
Two tests. One over programming stuff (writing binary search in pen for example) and one over general Windows use
