No. Suit jackets are designed to be worn exclusively with their matching trousers. Wearing a suit jacket with jeans or chinos looks like a mistake — the fabric, buttons, and pocket style are clearly 'suit' rather than 'casual.' Buy a blazer or sport coat instead.
Significantly less formal. A sport coat is designed for casual and smart-casual settings, while a suit is for professional and formal occasions. They occupy different tiers of the formality spectrum.
Generally no. Most job interviews call for a proper suit. A sport coat would only be appropriate in very casual industries (creative agencies, startups) where a suit would actually be overdressing.
Dark jeans, chinos (navy, olive, khaki, gray), and contrasting wool trousers all work well. The key is clear contrast between the sport coat and trousers — they should never look like they're trying to be a suit.
If you need formal wear for work, interviews, or events, buy a charcoal suit first. If your lifestyle is predominantly casual, a navy blazer (not sport coat) gives you more versatility. A sport coat is best as a third or fourth jacket purchase.
A blazer is solid-colored with metal or flat buttons and more structured construction. A sport coat is patterned or textured (tweed, plaid, herringbone) with natural-material buttons and softer construction. Blazers are dressier; sport coats are more casual.
