Coinbase Software Engineer - UI interview questions

Interview process was really professional. I applied through linkedin. First round was a simple programming round where the interviewer asked me to code a simple app using react. Second round was comprised of four rounds. 2 pair programming rounds and one system design round and one with Engg. Manager. While I did attend the programming round well I was nervous while attending system design and engg manager as the interviewer were really professional and sounded well. Anyway it was a great experience for me and I hope that I might crack future interviews here.
