Casper Software Engineer interview questions

Fairly straightforward. Personality screen with the recruiter, technical phone screen mostly about my background and current position with an engineer, take-home assignment, and finally an afternoon-long on-site interview. The assignment was specific to their stack which I think is unfortunate as it acts as a background filter more than competence or skill filter. The people there were friendly and intelligent. It was a pleasant process to go through but I found their focus on their technology stack in the final two stages of the interview to be off-putting.
