Nucleus Security interview questions

I had three interviews, during which I learned that the company has a no jerks policy and takes the values of accountability and open communication seriously. This did not extend to sending me even a brief note that the role was filled by someone else, however. I was surprised and disappointed by this lack of courtesy. Perhaps it was a fluke, but I feel I should mention it for the benefit of other people who may consider spending hours of their time interviewing with the company.
