I applied through a recruiter. The process took 3 weeks. I interviewed at Palo Alto Networks (Santa Clara, CA) in Feb 2016
Interview
The process takes over 3 weeks. One phone interview with HR and one technique phone interview with one employee. One week later, on site interview with four engineers and 45 minutes each.
Interview questions [1]
Question 1
The previous work experience, python, SQL and some algorithm questions. The first interviewer is a little bit arrogant. From technique perspective, he is ok. At lease he state his question clearly and write down all the questions and give examples. The second one does not tell me all the required information clearly. For example, one of the question is used by google (how to store 1 million of integer number efficiently).The original question says the range of number is less than 4 million and the ram is 1 million. But the interviewer tells me the range is "int_max". The mem space required by bit map solution increases 1k times due to his change. How can I resolve it? Another interviewer questions me from very beginning. He said the senior soft engineer should be able to work independently. Can you work independently? do you have such experience? I already have ten years work experience and most of the companies are larger than this company. I do not know how to answer this stupid question. Whatever I say, it is just stupid.Then, he ask some questions which are some bugs he has encountered. I do not understand the background and say no. Besides, he asked some questions orally and do not give example. My solution of course has problems as the I do not know what is the table looks like in the database.

1st round is with the hiring manager, gave a coding problem (variation of graph problem word ladder) and asked for improvement (multi-thread). Didn't need to run and test code.
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.
