Pirate Technologies interview questions

Prior to any live meeting I was given a task to work at home that took a few days. I think this was too much for first step, but I said ok and spent around 20+ hours total in 4 days. Then they just did not respond for more than 2 weeks, so I called them. They kept apologizing, saying they did not see my application and blamed the HR software. When they had a look, they told me they thought I did a very professional job and brought me to a live interview. Asked me so many questions and held for 1 hour, then told me they would let me know. Then they just never called, after all my effort, complete jerks. I actually even thought they were jerks while on the interview, because they were so gloomy and quiet, even among them selves.
