Place chicken tenderloins in a large zip-top bag or bowl and pour pickle juice over them. Refrigerate for at least 4 hours or overnight, turning occasionally.
Remove chicken from pickle juice and pat dry with paper towels. In a shallow dish, whisk together eggs and milk.
In another shallow dish, combine flour, paprika, garlic powder, onion powder, salt, and black pepper.
Heat 1 inch of vegetable oil in a large skillet over medium-high heat to 350°F.
Dip each chicken tender first in the egg mixture, then dredge thoroughly in the seasoned flour, pressing to adhere.
Fry chicken tenders in batches for 3-4 minutes per side until golden brown and cooked through to 165°F internal temperature.
Drain on paper towels and serve hot with your favorite dipping sauce.
