How can I name a person who always purposely says wrong about himself (or hide the truth) if you ask anything about him, but in really he is not like that.
Me: Buddy, how many coding programs have you worked-out for the practical exam?
He: I didn't prepare anything buddy, I'm afraid, I'm going to fail in this practical exam.
But he prepared well and scored full marks in the exam.
One more example:
He keep on saying he didn't look for a job change and all of a sudden comes with 2 offers in hand.
He prepared for a job change but always hide this from other friends
What is the suitable word for these kind of attitude person?
