I applied through university. I interviewed at Change Healthcare
Interview
Initially, they mail the student and ask for the availability. Before the interview, they let you wait in the reception with a guest identification. The interview is around 30 to 40 minutes. They ask about your experiences with self-projects and previous co-ops. They give a tour of their office and explain the work environments after the interview.
Interview questions [1]
Question 1
What are thread and process and the difference between them? What do you know about deadlock? How can you prevent them? Any knowledge about Dicom or PACS system?
Pretty easy, just a take home test about data structures and runtimes. They sent an email to me in order to do this, gave me a lot of time to complete it as well.
