Interview Preparation Tips

Interview preparation tips for other job seekers - This interview was a plant related and it lasted for about 45 minutes. This interviewer wanted to test both my knowledge and communication skills. Most of the questions asked to me were related to my B. Sc in chemistry and some questions ask me safety base. Luckily I was a able to answer most of the questions correctly. I tried to answer each question with examples and also used props on the table (like pens, paperweights, pen stands etc.) to explain my theories. It was my first offcampus interview, and I think I did pretty well for a fresher. You need to stay calm and should apply presence of mind. Please go through the job description thoroughly word-by-word and recheck your resume to ensure that you are a best-fit for the position.
