Interview Preparation Tips

Interview preparation tips for other job seekers - Well the interview process was completely online (Zoom Interviews) as due to COVID - 19 pandemic. The interview rounds conducted were truly in professional manner. The questions asked were based on my past experiences. They explained me very well with the kind of role that needs to be played for this opportunity. My advice to you all would be just stick to basic fundamentals of engineering & explain the same with the kind work you have done, in your own words which makes easy for you & can also boost confidence during the process. Even if you fumble a bit, still they do consider it understand it very well.
