MoonX Software Developer interview questions

Seems like interview scam to me. HR is the worst part of this process, does not have little sense how to schedule interview or communicate with candidates. HR is useless, scheduled interview without confirming the timing or scheduling before time. Called up and said come today evening for interview. Went through all technical interviews. Telephonic, architect interview, manager interview, hr round. After all this they say they are looking for lower salary.
