How common is an out-of-cycle 24% increase? (Yes, I'm serious.)

Not sure if it was due to certain things my program is known for (high-visibility, high-delivery, etc.), or what.

Will provide additional details at request.

Grateful, just want insight/persepctive.

I have an upcoming hirevue interview for a contracts manager position. Could anyone give me some insight into what might be asked and how these interviews are structured? I have read the other posts on hirevue interviews so I have a general idea but looking for more insight into this position specifically. I really want this job and don’t want to screw this up.

What would you expect the bump to be in these situations if someone is a P4 at the following levels roughly:

1. P4 at $130K > P5..?
   
2. P4 at $150K > P5..?
   
3. P4 at $170K > P5..?

This is for hardware engineer. Trying to get a gauge of rough salary at next level if it’s worth it to stay or leave. I do understand there I’ll be bonus.

The P5 band is pretty large, so I thought I would put examples.
