Infosys Java Software Engineer interview questions

before giving any interview they called and asked for my details regarding current company salary and experience. I asked for about 70-80% increment . They were ok with this .then they schedule the interview The interview had 3 rounds . 1st - technical round - basic Java concepts on exception handling, oops concepts, multi threading , Collections. 2nd round - Managerial round - project and work related things asked . 3rd round - they send me the email regarding some documents needed to be sent ( asked basic details, education background, then current salary and expected salary). -- I received the call and they told me like they will only provide 20% increment on the current CTC . So I simply decline the offer. It a very disappointing thing to give only 20-30% raise . Very bad experience.
