Lucid Software Software Engineer interview questions

I got a phone interview. Before the interview, HR would ask what programming language you're most comfortable with. I chose Python. In the interview, I got a python script including 3 coding problems. The difficulty was increasing. And I was asked to finished the problems in 1 hour (or 1.5 hours? I forgot, sry).

The process was fairly quick and pleasant. Started with a 1:1 video interview with an engineer who administered some coding problems and then left me for an hour to complete them. There were three DS&A problems, two easy and one medium-hard. After the hour, we spent some time discussing my solutions, next steps, and about the company. The final round interview took place remotely two weeks later. There was another DS&A portion for an hour, and a design/behavioral portion for an hour. The first was conducted by two engineers who asked two problems. The second was by an engineer and an engineering director who asked a design problem and a few resume questions, then chatted with me about the company more. Overall, the process was similar to other tech companies but the problems were a little more unique (not problems you'd typically see on HackerRank/Leetcode, except for one of the problems) . They were also a bit easier than what I have experienced elsewhere.
