Interview Preparation Tips

Interview preparation tips for other job seekers - First of all being confident !! Preparing one day before the interview how we represent ourself because we cannot know it could be face-to-face or online interview. Anticipating some questions prepare those questions just only to see how well you answer & taking proper time (not to hurry or being so slow) moderative, since it was my case so i was so focussed on this. They might confuse you somethings being firm on what you have done & also explaining on the projects what you done so far that will be challenging so i suggest to represent in slow & moderative way.
