How do I answer "why did you stop studying" in a job interview?

It's important to be honest and transparent about your reasons for stopping your studies. But sometime you can make a convincing reason so that you get the job.

You can start your answer with "I was the elder son in my family and due to family responsibilities" I had to stop studying. You can then go on to explain what those responsibilities.

For example, you could say something like, "I was the elder son in my family and I had to take on a lot of responsibilities at home, such as taking care of my younger siblings and helping my parents with their business. Unfortunately, this made it difficult for me to keep up with my studies, and I had to take a break from study for a while to focus on my family responsibilities."
