I applied online. The process took 3 weeks. I interviewed at Palo Alto Networks (Palo Alto, CA) in May 2023
Interview
The interview process was straightforward, first round with the hiring manager followed by on-site or full-day Zoom interviews. Unfortunately, the recruiter never bothered to call and explain what to expect in the interviews, even though the role required NLP expertise. After three weeks of radio silence post first round, they set up an on-site in the next two days without explaining the process. The interviewers were not interested in understanding if you were a good fit; they went straight to hackerrank questions. They even asked bad ML textbook questions. After the interviews, I never heard back from them.

2nd round was with 2 engineers, this was a problem-solving round. Given a piece of code, how to improve it (multi-thread again). Only need to write sudo code.
3nd round was with 2 engineers again, a system design round. Not a typical system design problem, more like a real problem in the work.
There was a conversation with HR, and then I was scheduled for an interview with a team leader about my technology stack. According to the stack, he asked me deeper questions to check my understanding. The next interview consisted of a technical question, posed as a LeetCode problem, and a coding question.
