Interview Preparation Tips

Interview preparation tips for other job seekers - The companies are hiring employees not machines correct. So the person taking interview should have conversation. I agree relating to process it is required but on the other hand some random conversation should also be initiated. And in this random conversation the interviewer should judge the candidate thought process and his ability to judge and go beyond the limits. And also please this is my personal request allow the candidates to ask questions on salary and other benefits because later it happens the candidate is not provided clear details and gets trapped. This create negative impact on the Companies image.
