About the skills they have if they work well with deadlines. Moreover, I would note that if a developer has a magento certificate, this will prove their professionalism. By the way, you can ask a few questions directly related to the work to find out if the developer is able to cope with real problems. For example, recently I wanted to hire a developer and asked him a simple question, I asked him to explain how to disable
product reviews on magento. He answered correctly, and I gave him a job. So, if you need more information or qualitative help I advise you to look on this option.
