Interview Preparation Tips

Topics to prepare for IBM Front end Developer interview:
  • React.Js
  • HTML
  • Javascript
  • OOPS
Interview preparation tips for other job seekers - Prepare your best. Do some leetcode and go through previous interview experiences. Get to know the IDE in which they interview you . Trust me that makes a lot of difference. Last part helped me a lot. You do not have to be a code parrot and learn everything by heart. The challenge is to receive a completely new problem and on the spot try to solve it. You will fail multiple times and you have to communicate with the interviewer about your approach. If you are close then he might give you a hint and voila the impossible problem would seem somewhat possible. All the best to everyone reading this!
