I applied online. I interviewed at Palo Alto Networks (Palo Alto, CA) in Aug 2021
Interview
An initial behavioral interview followed by 2 to 3 technical (coding) interviews. The technical interviews were all related to data structures and algorithms. The questions were reasonable and not extremely difficult.
Interview questions [1]
Question 1
Write an algorithm that given an array possibly containing duplicates, returns an array of the unique elements.
