Good luck with the job! I looked at their reel and it looks like they do some pretty great work. Would you be looking to work on the commercial side or feature film side?

Nuke apparently has a great slow motion module called Kronos that blows other plugins like Twixtor out of the water. That might be a cool place to start to get used to the interface. I also remember seeing a walkthrough of how they composited really complex scenes from the feature film District 9 in Nuke. It's insane how intricate you can get. There's definitely a lot of cool stuff going on in the post production world these days....
