Sample test questions shouldn't be shared, as they are essential to what the company requires as far as knowledge. But if you can read a word problem, and analyze exactly what is being asked for, you will do fine. Other questions were very normal. Describe a difficult situation and how you handled it. Tell me how you designed the solution to that issue. What are your weaknesses, what are your strengths. Why are you interested in HCSS? Basically, if you aren't interested after the tour of the premises, just leave. One last item, I was asked to sketch out a sort of diagram on a white board to illustrate a solution I referenced in a previous question. So know what you are talking about, and don't lie, as someone will pick up on it.
