Interview Preparation Tips

Interview preparation tips for other job seekers - It is pretty goodThis interview was a technical one but was majorly a stress test. It lasted for about 1 hour 10 minutes. The interviewer wanted to test both my knowledge and communication skills. Most of the questions asked to me were related to my B.Tech curriculum i.e. computer science related topics. He stressed a lot on the basics related to my project topic. Luckily I was 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
