Met during the career fair at school, got contacted for coding challenge, passed to first round of technical phone screen (was given a problem with about 4 subparts and an uninterrupted hour, interviewer came back after an hour and we talked through the code and approach for about 30 minutes), moved to second and final round - 2 back to back interviews each hour and a half (I think?) and each interview had two interviewers one senior and one junior engineer (I think).

One was coding interview and one was design interview. Overall, a very positive and professional interview process, out of all companies I interviewed with, I rate Lucid's interview experience the best along with Google.
