Future Software Developer interview questions

This interview was for the DC office... The first step was a 45 minute phone interview that mixed culture fit questions with technical questions. The 2nd step was a 2 hour coding interview. The first hour was with one developer the 2nd hour was with another developer. The 3rd step was another hour long coding interview and then 2 30 minute interviews with hiring managers. After all that they said the would get back to me in a week. They never did and they never replied to any follow up emails. Very unprofessional and disappointing to ghost me like that after putting in that much effort. Show some respect and let me know if I got it or not.

A phone interview, asking personal question involving the professional background in the job type. After that few knowledge question which are related to the field. After that I don't know what's going on since they never called me back. There's something called "common courtesy", apparently not all the companies are familiar with this term. In this context it means that the applicant is waiting for your answer. Even if it is a negative one, let him know.
