If you mean in Supercruise on the way to the Maelstrom, interdictions occur all the time! That video does not show them, and to be fair I started mine also just before dropping at the Maelstrom, but it happens often in a Maelstrom system. Normally it is Scouts or a Cyclops, or occasionally a Basilisk or Glaive. Interceptors can be escaped starting from around 350 speed because they take a moment to deploy the Swarm, and only a heavy can
low-wake away from a Glaive.
If you mean amid the Maelstrom, it is all about staying cold and quiet, and staying close to the Titan but not too close to its maw. Drilling the storage chambers and rescuing the pods will attract a lot of attention, and those vessels will attack if you stray from the Titan or approach the maw. Rising above 20% heat will also let the Titan turrets target you even while close, and the Hunter-class vessels will use missiles.
The Anaconda there likely was chosen to be the best non-Navy option which has over 20 mass-lock factor; it is a bit slow though. Easily the Imperial Cutter is the best at this, and the Federal Corvette is a great second if it can be made quiet enough!
