Pocket Gems interview questions

I applied online and get online test about two days later. The online test is easy. I spent about one month to schedule phone interview. Only one question in phone interview, answered not prefectly. I got rejection two days later.

the process of the interview is quite compact, first it took 5 minutes to see my resume, then, follows 2 algorithm questions, the first one is quite easy, just if a string is the substring of another string, the second one is pretty special, and I did not get the offer because of it.
