When my previous employer closed the doors and laid off the entire workforce I was contacted by someone at Lucid and invited to apply for a job. A time was arranged for a 3 hour interview. The first part of the interview was a three part programming challenge and an hour to get as much done as possible. They let you choose which language you want to use, I chose C++. The first two parts were relatively easy, the third part was the most challenging. I didn't quite finish everything in the third part, but I guess that was good enough. I felt like the amount of coding necessary to complete everything was pretty aggressive for the time given, but the third part in particular was actually pretty fun.

After the coding part of the interview there were two more interviews where two people ask technical and experiential questions. Overall the interview process was friendly and as pleasant as an interview could be. The people who interviewed me left a very favorable impression of Lucid's employees. Lucid reached out to me within a few days with an offer and gave me a couple weeks to respond.

The most difficult part of the interview was the coding challenge. I won't disclose the details of the question, but it was challenging and I enjoyed the challenge of getting as much done as I could in the allotted time.

If you aren't used to coding under pressure, you might want to join HackerRank and try some of the challenges there to get some experience.
