That looks like some really good work! You've got a good start with that. You should do some detail drawings of some of the individual components. The side plate with all the cutouts, properly dimensioned, would be a real selling point.

When you go to an interview, be prepared to talk about what was challenging to do and what constraints were used in the model assembly. If you were involved in the decisions about how to make that part of the robot, you should talk about that and why you decided to build it they way you did.
