Parangat Technologies interview questions

Interview was good I cleared all the rounds but as HR asked me what is your expected salary I said x but she offered me x/3 after all the interviews done

My scheduled time was 1PM for an interview. I joined the google meet at sharp 1 PM leaving my schedule tasks of office just to give an interview but no one from Parangat Technologies appeared and in turn after 12 minutes call automatically disconnected. Sheer unprofessionalism from them, no time value of others. Infact HR also didnt turned up at 1PM to confirm at what time the panel will join. Pathetic!
