Pocket Gems Software Developer interview questions

After finishing the OA, got a call from one engineer to begin the interview. Actually the interviewer seemed to be not familiar with the question given and had a long time explaining the second question. Actually this company gives the OA to everybody and seems to let engineers try to interview as many people as possible to get, experience?

Pocket Gems is very generous with giving interviews. My friend in PocketGems referred me and I received online coding test instantly. I did some preparations for several days. Before I was going to do the coding test, I found the ESTIMATED time of the test is 1h50min, but the ACTUAL time they gave is 1h15min! I emailed them asking if this is intended. After two days I finally got the response saying "This is a mistake, we fixed it". Do you believe it? If you believe it, the two-day delay and the mistake are still very unprofessional. Personally I think setting the time to 1h15min is a way to raise the hiring bar intentionally and sneakily. I don't want to judge people like that, but the thought made me feel uncomfortable. The coding challenge is not too difficult, but it's not trivial. I made the most things right and I was 90% on the way (Minor bugs prevent my code passing the unit tests). I explained the situation and hoped they gave me a chance for the phone interview, because I heard some people still got phone interviews without finishing the online test before. But the next day, an auto generated decline. Every email during the process was auto-generated except the email "we fixed it". Yeah they are generous with giving interviews, but they are also generous with declining people.
