+Key points to be successful in the coding interview:
+* Drive the interview; communication is more important than anything so If you need to be quiet to think, that’s great – just let the interviewer know. 
+* Explored the problem; Talk about what you are doing throughout the interview.
+* Reason about your decisions and share your reasoning.
+* Think about trade-offs; Find and fix the bugs by yourself.
+* Practice under time pressure; Put yourself under time constraints and If possible, have a mock interview with a friend to simulate the interview experience.
+* Manage Your Time Effectively; start writing a working solution, then iterate and improve it as you go.
+* Break down the problem into logical chunks and solved them
