Hi Guys,
I have Palo alto Networks interview coming up for the positions Senior Staff UI engineer.
The recruiter mentioned the following focus, React.js, leetcode and System Design.
React and System design are pretty straight forward.
I would like to know what sort of leetcode questions will the interviewers choose? like easy, medium or hard? and are there any commonly asked topics like lists, arrays or something?

Thanks in Advance!

MY EXPERIENCE:

1 initial technical round- online:
Create a wizard component with steps highlighted as the user clicks on next and previous buttons.

4 onsite rounds- In person:

1. SD: Design the search and filter section of a ticket management system like Jira or clickup. Focus was how you'll design the filters with the grid data which received in chunks. How efficiently will you design the dropdowns with hundreds of thousands of data.
2. React: Build an app with a side nav. side nav should have two or three pages and should be able to switch between pages. And the first page should have a timer ticking every second and once the user navigates to another page the timer should stop and then should resume when we navigate back to the page.
3. Leetcode: Iterate Nested lists, print the lists with indentation based on the level it is in. and every parent object should keep count of the children including grandchildren and so on... so sort of recrussion and then send back the count of entities each level to its parent.
4. Behavioral: general questions like tell me about a time.... and tell me your goals for next role...
