Pocket Gems Software Developer interview questions

I got a headhunter to contact me on LinkedIn, he was very helpful. The first step is to do an Online assignment. And about one week they do the phone interview.

I took the phone interview of this company on 24th August. The interviewer was 5 minutes late. And he seemed tired and not interested in the interview. First he let me to ask questions about the company, I just asked "how many years have you worked int the company", then he gave a number then just began the interview. He gave me a code problem, I finished it within 15 minutes and explained all the details in it to him. He said "seems good". Then came to the end of the interview. Then the next day I received a rejection letter. The interviewer seemed impatient and not interested. The whole interview lasted for less than 30 minutes and was not that pleasant.
