For your interview, make a study-guide with concise notes and pointers about all the important concepts you need to know. It’s good to take a glance at the guide and brush up on the content before you go in. Close your eyes and take time to make a mental mindmap of what you have just read. That way, you’ll boost up your confidence and shake-off any nervousness. Right before the interview, just relax. Take a few deep breaths and be confident about yourself. You will do just well!
