Pocket Gems Software Engineer, Backend interview questions

I got two interviews from pocket gems totally for the same position. One got about three month ago and second got recently. My advice for candidates is the DO NOT WASTE TIME FOR THIS COMPANY. Totally, the two interview are not too hard. I got them from recruiter. Each interview, I got two round phone interview. After that, I got thank you letter and "not move forward email". All the four round interview, the interviewers were satisfied with me and my answers were also correct. Not just me, my friend also got same situation with me. Even if pocket gems offer another around interview to me, I would never take it. It is just a waste of time.

Applied the position on glassdoor. A recruiter contacted me after one week. I had a phone interview. Some basic information questions. Then coding questions. I finished two coding questions in 40 minutes and the interviewer agreed with my solution. After two day, I got rejected letter from recruiter without explanation. Very poor experience.
