Hi, my dear friend.
Yesterday you told me that, you were called for interview from the reputed MNC Company. You felt so nervous and obsessed over the interview.
Just relax. Do not push or rush yourself for anything. Just realize that this not a must win situation. You are already comfortable of current job. So be cool. Nothing is going to change your life. This is just another company. This is just another interview. This is just another day. Nothing special. No need to boost your self. No need to be obsessed by interview thoughts. Just relax. Joining or loosing this big company is not going to change your life upside down. God can give anything and remove anything from you. Be balanced and keep your mind calm.
No more nervousness. Your mind will be free soon. You will be so comfortable, expressive, audible and fluent in language during interviews. You will be as you. Remember you will get only what is due to you. So try without expectation.
