CARFAX Software Developer interview questions

1) Phone screen 2) Virtual video interview for 90 minutes 3) On-Site interview Phone screen was just the usual. Experience about my previous work, what I am interested in and so on. No technical questions asked. Virtual technical interview - In-Depth questions about previous projects and why was I planning to switch. The technical challenge was to complete a couple of APIs (GET) whose skeleton they had provided. I remember it being the Movies API to list in a lexicographically order and also eliminate the duplicates. On-Site was in Columbia, MO. 4 Rounds. One-on-One with the manager, panel interview with 4 team members, technical challenge with the idea of "pair programming" to a) fix an error and b) write unit test cases for an existing functionality and interview with the Director.
