Interview Preparation Tips
Interview preparation tips for other job seekers - This interview was a technical one. It lasted for about 45 minutes. The interviewer wanted to test both my knowledge and communication skills. Most of the questions asked to me were related to my B.sc (statistics).He asked on the basics related to my project topic and some current affairs based on my field.Luckily I was able to answer most of the questions. I tried to answer each question with examples. It was my first oncampus interview, and I think I did well for a fresher. You need to stay calm. Please go through the job description and recheck your resume to ensure that you are a best-fit for the position.
