Before choosing a team of developers, you need to conduct not just an interview with each of the applicants, but also give test tasks to the most suitable candidates. Ask them a series of questions that you are interested in and that will convince you of their knowledge about Web3, and then when they answer all your questions, you can ask them to perform a test task that will help you to decide for sure whether to hire them or not. By the way, I can recommend you one very good Web3 dev team that you can consider as one of the applicants. Here is a link to their website https://pharosproduction.com/.
