Company cancelled interview 3 minutes before call when they knew 24hours ahead of time that they had already filled the position. Extremely unprofessional behavior from this company with no consideration for my time spent.

First interview was with VP of Engineering and involved two technical problems, write a basic SQL query, write a basic function that processes some backend logic, syntax was not important. More interested in problem solving than having runnable syntax-perfect code. Also Q&A on why SamaCare and behavioral. Final round was a panel with culture / behavioral round. Then a system design round with CTO where I explained the architecture of a system I worked on as well as pros/cons of each architectural component. Very high level. Final round was another coding problem involving working with JSON data and writing a function in any language I liked (I used JS) to process the data. Total of about 4 hours of interviewing. Par for the course for software interviews.
