I applied through a recruiter. I interviewed at Palo Alto Networks in Feb 2021
Interview
Two phone interviews.
First round contains a simple C programming question and TCP question. Second round all asks about system & network stuff. (You have to be very familiar with TCP, also please pay attention to SYN attack prevention, I've been asked twice.)
No algorithmic questions. OA just contains simple programming problems.
Interview questions [1]
Question 1
How do you prevent SYN attack?
What's the default window size of TCP?
Memory layout of a process.
very smooth process, they have a help session to talk about interview process and how you can prepare also warning not to use AI etc. it was very informational and helped ease the nerves quite a bit.

Question 1
asked me how i had a problem with an employer and solved it
Telling about myself and asking questions to an interviewer, telling about the job I worked at recently.
In addition, there were coding and architecture questions.
Overall the interview was average, the people were nice and it was a good experience.
An easy tech interview starting with a friendly chat, simple coding questions, and clear expectations. The interviewer guides you, values problem solving, and focuses on understanding rather than trick questions.
