This is a technical interview where anything can be discussed related to web development, computer security, operating system, data structure software architecture, and system design principle. You are not expected to answer every question so don’t worry if you miss a few. Duration: Interview duration is generally from 15 to 30 mins. The short interview doesn’t necessarily mean you did badly. So better to answer questions to the point so you will get more questions and therefore more opportunities to present your knowledge.
