Interview Preparation Tips

Interview preparation tips for other job seekers - I would suggest, don't give up. If you are given any questions then think to give them your solution. Interviewers are too supportive, if you get stuck at any point they will give you hints. They won't judge on this basis that outputs are correct or not maybe you will solve it partially but you will get some plus points for your approach also.
