I originally applied for a different position, and on the day of my interview, got a call saying that the other position had been filled and this one was available. The interviewer was incredibly kind and was easy to talk to. He asked simple interview questions and didn't overcomplicate them. It took about 25 minutes and afterwards he told me that I would be contacted the next week if they wanted to move forward. This interview was on a Thursday; I got an email the next day stating that they would like me to do their case activity. I was given the case activity on Friday and stated that I had until Monday to complete and submit it, and to ask any questions; they were happy to help. I emailed a question that was important for the case activity on a Sunday and didn't receive an answer until Tuesday; the day after the deadline. I told them that I already submitted it by the deadline and I also left a submission note.
