I applied in-person. The process took 1 day. I interviewed at Palo Alto Networks in Sept 2021
Interview
The first stage of the process is a codility test, the test is performed on the home computer at home, it is 90 minutes 3 questions.
The questions are not very difficult, but it is necessary to pay good attention to the efficiency of the solution (complicates the solution very much), and to extreme cases. A total of 3 programs to compile and work well in 90 minutes is a bit challenging.

I applied online. The process took 3 weeks. I interviewed at Palo Alto Networks (Tel Aviv-Yafo) in Jun 2024
Interview
Interview process:
- Phone call with the recruiter.
- Phone call with the team leader.
- Home assignment with a deadline of a few days.
- Interview at their offices with the team leader and his manager.
I had a big flaw in my assignment, which probably caused to me not passing.
I answered the rest of the questions properly, even as requested to code.
During the interview, it was pretty clear that I wasn't the candidate they were looking for, but messaging in front of me while glancing at me felt unprofessional. They could have waited a few minutes for me to leave before doing that.
