I applied online. The process took 2 weeks. I interviewed at Juniper Networks (Sunnyvale, CA) in Jul 2019
Interview
In-person interview, many rounds.
The first two individuals were reasonable and we talked 45 mins with each. The third individual began to ask all sorts of beginner C questions, like "where the semicolon is missing"? (she showed me a printf statement w/out a semicolon), < was confused with <=, etc. It's really strange to ask such high school level questions a person who says that he knows C/C++ 10 out of 10. Then she proceeded to ask various questions about MAC addressed in ethernet packets. I happened to know this, even though this wasn't mentioned in my resume. Then she proceeded to ask some very elaborate and specific questions about some enhanced router designs with multiple ethernet ports, and NAT translation. I couldn't understand what she was asking at all, since this must be related to some specific equipment that they have. Then she proceeded to ask a question how to design an elevator. At this point I didn't feel like explaining to her the linear optimization program that could solve the elevator algorithm problem, and I interrupted this interview and left.
The questions were all over the place, mostly either the beginner questions, or irrelevant questions questions about some specific equipment that I've never had a chance to have experience with, and didn't mention on my resume. It seemed very dumb and meaningless.
The interview didn't make any sense, was all over the place, and I interrupted it myself. I didn't feel like I wanted to be there.
Most employees are from the countries that send a lot of H1B workers. I think that Juniper interviewed me as a way to prove that they can't find any qualified candidates in order to bring more H1Bs. Otherwise, it's very hard to logically explain such interview.

Interview
5 interviews total consisting of coding and general background questions about work experience. They asked OS questions and questions about my background. Questions about memory, cache, Networks, threads etc were very common.

Interview questions [1]
Question 1
The students who clear the written round are called for a Technical Interview. To clear this round you should be clear with your basics. You should be prepared with Data structures and Algorithms, DBMS, Operating Systems, and computer networks. You should be well prepared for system design problems. Students will be expected to write codes in the interview. They also ask questions from resume. They frequently ask questions about your previous projects. You may be asked puzzles in this round.
5 interviewer panel. Covering past experiences, domain expertise, and behavioral questions. 1h each. No coding questions. Focus on system design and deep dive into protocol knowledge. Then final call with recruiter to discuss numbers. No relocation package.
