Hi, I have done the same exact thing. It was tough for me when i went for the first few interviews after the resignation. They were keep on asking why?why?why?. But should not put the blame on previous management or anything. Easiest excuse i had was " After working for two three years i needed a break. so i decided to go on a vacation to UAE to visit my family".That would be tough for you also. But be motivated & everything going to be ok. I got a good job within 1 month. Cheers!!!!!
