I interviewed with 5 different people in total, including two pairs. It took 3 hours total. It was pretty standard. The questions were straightforward and intelligent. There were not gotcha questions. I have interviewed at Microsoft, Amazon, Oracle, LinkedIn among others, and it was pretty similar to what I have seen at big tech companies.

I have definitely had a mix in experiences before. In the past I had had interviewers who did not introduce themselves or greet me by name, but were overly skeptical, vague, or supercilious. Lucid's interview was very positive however. They listened and seemed sincerely interested in me. They took time to answer my questions and tell me what they honestly liked about the company.

The process was a little informal. For example, it was difficult to find the exact office they were in at the time. I know they were a startup and mainly a bunch of engineers rather than a formal set of recruiters however so I understood. Dress was casual.

I had to code on a whiteboard an algorithm.

I was asked several language questions.

I was asked about my background.
