It depends. I usually end up behind the target, but sometimes, it'll put me in a spin as I fall into normal space. Sometimes, it doesn't.
The question on interdiction is whether you are submitting to it, or fighting it and lose. When interdicted, I'll set speed to zero, drop out, and my FSD cooldown is pretty quick. If I fight it and lose, then I'm out of fleeing commission for a bit.
How are you addressing the interdictions? If you're basically unarmed and hauling cargo, do the immediate submit, throw three pips to system, three pips to engines and don't play the "what does this guy want?" game. Boost, use flight assist off to keep more momentum, boost again, fire FSD, boost again, jump. Even if the pirate, pvp, NPC starts firing, you can have some range, and get back into SC quickly.
