Deloitte Automation Engineer interview questions

After profile being Shortlisted by recruitment agency,Got a call for technical interview. There was F2F interview for the same mostly technical.I was asked about previous projects and was asked to write code.

Attended interview for Java selenium on 4th of August..the way they conducted interview was horrible..they had called around 1000 candidates for interview..so they were not able to manage the crowd properly.my slot was at 2.30 pm but when I entered there I could see that people were waiting from 10.30 am as well.. Anyhow I got a chance to attend the interview at 6.15 pm..the interviewer did not ask much questions..she asked me what did you work on your last project ,I explained.she asked some basic selenium questions,I answered.she did not even ask me to write a program neither in Java or selenium.The interview duration was only for 10 mins.But she rejected me..how she can judge a candidate without asking anything..The fact was that they were hurry to go home so they were not selecting candidates for the next round.Irony was that around 100 candidates were in the waiting room at 6pm..but within 30 minutes they vacated the room by rejecting the candidates.Even for some candidates HR guys were asking questions like what is test plan and all.. In the evening they made a plan and they were giving feedbacks to maximum people saying that , you will get a call on Monday..For my friend the interviewer itshelf told that you are rejected but HR guys gave feedback like you will be getting a call on Monday..How is it possible.. Simply they were playing with the candidates.
