ALTEM Technologies interview questions

They are very creep people. They don't respect time of others. They took 4 rounds of interviews. One telephonic round and 3 Skype call. Then they asked to visit their Bangalore office. After visiting Bangalore office, they just did normal conversations for 20 mins and asked to wait. I waited for whole day but they didn't respond anything. Finally in evening HR asked me to leave for the day. Next day she texted me that we are not taking your profile forward without any reason.
