Lyft Frontend Engineer interview questions

They gave me some material to study related to systems, algorithms, and data structures one week prior to the interview. I studied all these concepts expecting to be solving an algorithms problem in the interview but went another direction and had to implement a complex component with plain javascript and HTML

One phone screen ( asked about the background), one technical screen. The interviewer was very helpful during the whole process and tried to help out whenever I got stuck. It was 1 hour long.
