Tempus AI Data Specialist interview questions

I skype interviewed with 4 different people (almost 2 hours). The interviews mainly consisted of them complimenting my skills and explaning how this job is "boring" and "mundane" (which is weird). They explained to me that the following step would be to go to Chicago to interview me within the next week. They gave me files containing info on sample cancer patients. I had 24 hours to analyze their symptoms and insert them into an excel spreadsheet. It took me about 6 hours to complete and submit. They replyed they would get back to me within the next few days. Didn't hear back until my rejection email 5 months later. This was in 2017 but based off more recent interview reviews on this site their poor business practices havent changed much. PS: They wasted 8 hours of my time but couldnt take 5 mins out of their day to respond to my emails for 5 months. This practice is a reflection of their work ethic: They probably overwork their employes and underpay them.
