Exploding offers are an exploitation tactic intended to pressure you to commit to doing what the offering party wants ASAP, or else what you want will go away.

Exploding offers are an exploitation tactic intended to pressure you to commit to doing what the offering party wants ASAP, or else what you want will go away. It's OK for something like a firesale at your favorite retailer, but definitely not good on a more intimate scale, like a job or investment. If they actually want you, they'll let you take your time regardless of what their offer says, and an exploding offer is a big signal that you probably don't really want to work with them.
