Tudip Technologies IOS Developer interview questions

The very Bad Interview process, They have called for the interview on working days and when I reach there they have no time management and my turn come after 3 hours. Also, there are only 3 interviewer who takes interview for all technology via searching the questions over the internet. And after asking 6 question within 10 min they have finished my interview. Don't know how they have measured my skill by asking just 6 simple question.
