Completely f*d up an easy accenture interview due to overconfidence

I have 5 years of exp as an angular dev and recently i have been laid off and this is my last month and i had applied to accenture through referral out of the blue suddenly HR calls me yesterday and says that today is my interview i ask her to reschedule to a later date but she doesnot agree i then go ahead with the interview thinking it will be easy and it was but i had not prepared and this is my first time giving an interview after 2.5 years , the interviewer asked fairly easy questions i couldnot answer 5-6 questions because i didnot remember the names of the terms properly and believe me i have cracked very hard interviews in the past but this time i was just not prepared, results came out and it says i couldnot clear the interview I am very much ashamed and disappointed in myself that i took this interview chance very lightly as i am currently in desperate need of a job. Feeling very sad and ashamed that i couldnot clear such an easy interview and i have worked on so difficult tasks in my company it was so dumb of me .
