I have an onsite for DocuSign coming up and they are composed of 50 % system design and 50 % coding. Does anyone know what type of system design can I expect ( OOP & Scalability ? ) for SDE 1/SDE 2 level ? Also what kind of coding ?

Update:

1. Hr contacted me and setup a phone screen
2. Phone screen 1 hr similar to jump game and database heavy read system design
3. Virtual Onsite ( medium - easy coding, anagramas, duplicates, frequencies). C# related question which I was not expecting.
   1 week after my onsite, I was rejected and Docusign posted the same position with higher requirements on the same day of my rejection
