**DO NOT DO THIS** You are interviewing at a bank. They SHOULD know better than to ask you for this information. What is possible, but highly unlikely, is they are trying to gauge how much information security training they should give you. If you cave in (they will put some pressure on you) and you'll be flagging yourself as needing extra training. Don't be caught in the game where you ask for reasons. There is no reason why they need both sides of your bank card. So don't even invite them to say things that are not true and attempt to confuse you. Regarding the card, there is often not just a CVV number, but there can be other security measures on that card, that you leak by trying to be clever, taking a screenshot, and blurring things out. For instance, on my Visa card, there is an additional code that some merchants use to verify the card is in my possession. Simply send them your **bank name**, **branch name**, and **account number**. If they need more than that, contact YOUR bank, and ask for their advice.
