Edelweiss Financial Services Java Middleware Developer interview questions

Worst interview in my life. Better not to go to waste our time. It took me more than 1 hour to reach to interview venue and the interviewer took only 4-5 mins to take interview. She told she needs to go in a meeting than why they call candidate to come for interview if they don't have time and after 4-5 mins she told you can go now.
