I applied through a recruiter. The process took 2 days. I interviewed at CareATC (Tulsa, OK) in May 2015
Interview
Short, fast paced, and not overly technical. Initial interview took place in the office and was very light on technical questions. Very informal. There is quite a bit of grilling around SQL especially, and some general knowledge questions.
You answered a 7 to the SQL, answer the following. How can you tell why your query is running slow? What is a CTE? What is an outer apply? What is the difference between a join and left join?
