Overpreparation for an interview may lead to rejection.
A lot of people complain that they prepared a lot on any aspect for an interview.Everything went good but still they were rejected.
Here,there is a suggestion from my side not being realistic or not being yourself might be the reason for this.
They are not there to hire machines who can work 24×7.Most companies will not care about your answer but the approach you are following for moving forward.
Prepare for interview.Learn the technical things required for it but use your own intellect,your own understanding.
