The process for this is usually like that:

• Software dev team lead: "We need another senior frontender."
• HR person: "Ok, what are you looking for?"
• Software dev team lead: "Someone who knows how to use Angular."
• HR person: "Great, so which version of Angular are you using?"
• Software dev team lead: "Version x.y.z"
• HR person (thinking, not saying): "Ok, so senior means 5+ years, so 5+ years of version x.y.z it is!"
• Also HR person: “Why can’t I find anyone who’s qualified?”
