I went for F2F discussion for the Java developer position. I was having 3.6 yrs of experience.Interview was scheduled by a consultancy. I reached at venue sharp 10 AM. I went 1st round for technical discussion. Technical guy who was taking interview was too rude and short temper. He initially see my resume and started. Though I am from a payment company. He started asking on various payment integration. Though I told him I am working at product side. Payment team is different. He was not listening at all and asked questions totally related to payment domain not from coding. I told him as if now I attended lots of interview they asked about coding only. He shouted like any thing. By showing his attitude I know that he doesn't want to take interview and just playing with me and wasting my time . Once he done asked me to wait but I told him I will not wait and leave the venue as I know the feedback. Later hr called where r you , I told him that I left the venue. As everyone know that they will ask like any thing in the interview and later after joining put into a support project then think how can any one know all parts of a project. If I am having all the payment domain knowledge from starting to end then why should I go for a company interview and beg for a job and work like a slave. I can develop mine own product and open the company and hire these slaves to work for me. I totally got irritated and spoiled my weekend.
