Technical interview questions and answers are important for a Visual Basic Interview because many companies still use VB for maintaining legacy applications, automation tasks, and Windows-based tools. Recruiters expect candidates to understand syntax, variables, loops, functions, event-driven programming, and form design. Visual Basic remains relevant for industries that rely on older but stable systems, so questions from VB often appear in interviews at companies like TCS, Infosys, Wipro, Cognizant, and Accenture. This guide includes frequently asked Visual Basic interview questions with simple, clear explanations that help freshers and job seekers prepare effectively. These questions will strengthen your understanding of VB fundamentals and improve your performance in both technical rounds and project discussions during campus placements.
