When you’re effectively interviewing for a lawyer and perhaps you’re visiting different websites and talking to different lawyers, the key thing is to have a sense that they understand that area of the law, ask them questions about other cases perhaps, that they’ve had recently. Some of the stories that they can share with you.
The really experienced lawyers will be able to compare your situation to other situations that they have faced in the past, and they’ll be able to draw from the wisdom and knowledge and experience of those other matters to make a real difference for your case.
On the other hand, if you’re talking to someone who really doesn’t know much about that area of the law, they should be honest with you about that. And if you have a sense that perhaps they’re trying to talk up their ability, and aren’t able to actually give you concrete examples of how they’ve helped other people, then trust your instinct and maybe look for someone else to help you.
