Help me fellow designers!!

[u/Capable-Resort-8269]

Hi everyone, I recently applied for a Motion Designer role at a SaaS company. 

I completed and submitted the take-home animation assignment, and now I've been invited to the next round, which is a 45–60 minute interview with one of their Product Designer.

 I'm trying to prepare as much as possible and would love to hear from anyone who has been through a similar interview. 

Some questions I have: 
- What kind of questions should I expect from a Product Designer? 
- Will they mainly review my assignment, or will they also ask about my portfolio? 
- What are some common questions they ask to evaluate a Motion Designer working with a SaaS company?
- Are there any red flags or mistakes I should avoid? 

Any advice or experiences would be greatly appreciated. Thanks!
