Here's the deal: You have to know SQL. By all accounts, and according to people within the company, they are no longer hiring people who do not have previous SQL experience. If there is one thing that I can point to that probably cost me the offer, it is that I have not used SQL in a while, and it showed. Everyone with whom I interviewed asked SQL questions. They will give you a set of EMR (Electronic Medical Record) data (2 or 3 tables) and ask questions about how you the tables might be manipulated to provide information. So you not only need to know how to select certain data types and columns to provide insight in theory, but you also must know how to construct the correct select statement. Expect questions on inner/outer joins, unions, subqueries, aggreagtor functions including how to use sum and/or count with group by. If you don't have solid command of SQL and a good bit of fresh, current use, you are probably wasting your time. Yes, SQL is a rather small language in the DML context, and something that can be picked up rather easily, but probably not quickly and completely enough to impress in the interview. Bottom line: don't expect to fake it till' you make it.

The interview was a structured interview with manager following the paper outline. The manager inquired further to some of the questions along the way though mostly went one level deeper with followup questions. Most the questions that I remember were experience based with some personality based. No big deal the interview was relaxed and the role required dynamism and a strong person which almost seemed hypocritical.

Example of the SQL exercise: For accounts that are reported exactly n times in 2012 (n = 1, 2, …), what is the average amount spent by these accounts for different payment types in different months in 2012? What percent of the monetized accounts gets reported before they monetize? Example of the brain teaser questions: sum of 1-99 sum of a 10x10 matrix, 1st row and 1st column are 1,2,...10. where the first row is: 1,2,..,10, the first column is: 2,4,..,20. and the last row is: 10,20,...,100. sum of a 3 dimension with rows and columns from 1-10 just like the previous question. pets doubling everyday. at day 25, it reaches to the capacity. how many days it will fit in half of the capacity. clock, degree between 3 and 3:25 clock, degree when hour head and minute head overlap at 3-4 oclock.

I was asked a great and interesting question that I will most likely use in my hiring process going forward that really demonstrates how one thinks and responds to a analytical problem. You have 9 balls and a balance, one ball is slightly heavier than the rest, with only 2 chances on the balance find that ball. The interviewer helps think through and everyone gets to the answer by the end but it really displays how someone works through a problem.
