The biggest challenge I faced in my last job is when I used to call the clients, they used to think that we are a spam caller. So making them believe that I'm generally from the legal age was a task, it was a challenge. And sometimes the interaction, the conversation was not very pleasant. They used to hang up on me and I had to call them again, making them believe. But every time, I dealt the situation with all calmness and all patience. And yeah, I mean, it took time to make them believe, but still somehow I managed it. And I resolved my problem and I got my job done.
