What about the time it takes for interviews? Is it being disrespectful to take up an hour of their time for an interview? What if you do a 2nd interview for another hour? What if you have a 3rd? It's not unusual to have 2 or 3 interviews before hiring. What if you replaced one of those hours with a coding task that should take under 1 hour to complete. Is asking for 1 hour disrespectful to their time? Why is asking for 1 hour of their time to code different than 1 hour of time for interview?
