          Interview Experience
          3 Algorithm coding rounds, where the first round was way too easy.
            People who took  the interviews were very nice. They wanted to see the approach and the will to solve the problem. They actually helped to think to some extent in the  right direction.Then they put up some questions like: Find the anangrams of a string, reverse each K nodes in linked list, if location of leftmost node is origin, find the location of the root.
          Find the possible pattern locks in the smartphones. for ex-125, 12, 7, 459, 1236, etc
          Interview Tips
          Be calm and confident. Do not just keep quiet while solving a problem. Keep talking to the interviewer about whatever is coming to your mind. Try giving an interview to your friend. Do not rush to a solution. Think before you speak. If you don’t know anything, admit it. Don’t try to fool the other person by telling him something he didn’t ask.

            General Tips
            Try to maintain your cgpa as good  as you can. Some companies do have cgpa criteria. It will also help you when you switch your company. Summer training also does help. For the projects undertaken, it depends on the field of project. It would help if it is related to the company you are sitting for. It is always good if you have worked on something new. If your project is currently in it's working state, then it's an advantage.For instance, an online website is far better than an offline one.
