REX Software Engineer interview questions

Was reached out by in house recruiter on LinkedIn, had a 45 minute coderpad interview online, then went to the Redwood City office and had 4 1:1 interviews. 2 DS & A 1 Behavioral 1 System Design Overall standard process, but I really liked the team. Lots seemed to be ex Google, FB etc., but what stood out was their humility and authenticity if that makes sense. Usually system design and behavioral feel really weird like you are being judged, but in this interview they felt like conversations where I learned a lot. Ultimately I went with another company because I was more interested in that mission.
