It's very easy - everything is behavioral, so you should be safe if you use a STAR response for each question. They send you information ahead of time on what to know about the company, so that makes it a lot easier as well. If they don't send you anything, make sure you are familiar with their K Power to Grow model as well as their K Values - most of the questions are centered on these two ideas. I did not have a phone screening and instead went straight to a panel interview. Everyone is very friendly and they gave me my offer within three days.
