Interview Preparation Tips

Interview preparation tips for other job seekers - I had 6 rounds of technical interview . Each round of 1 hr or more. In all the rounds I was asked to write proper programs (Sometimes on HackerRank, sometimes on an IDE, sometimes just on a text editor.) . Questions were designed to test problem solving abilities and proper use to dataStructures and coding basics. Lot of emphasis on writing efficient program with least time complexity possible.

During preparations, its important to understand basics of different dataStructures and how to efficiently use it in your programs . For practicing interview problems, I referred leetcode and geeksforgeeks . Solving different kind of problems from these websites really helped me. Dynamic Programming is also an important area from where lot of problems are asked in interview.
