Seeing the URL shortening service design question caught me off guard at first, but it turned out to be a lucky moment. Just a few days prior, I had practiced a similar architecture problem on PracHub, so I felt somewhat prepared to tackle scalability and data consistency aspects. The process included a recruiter screen, followed by a technical interview focused on system design. Overall, the questions were manageable, but I didn't end up receiving an offer, which was disappointing. The experience taught me a lot, though.

Question 1
Design a URL shortening service (similar to bit.ly). What components would you include in your architecture, and how would you handle scalability and data consistency?
I had the pleasure of interviewing for the Senior Node.js Developer position at Netflix. The process was well organized and structured.
The first stage included a phone interview with HR, where we discussed my professional achievements, experience with Node.js, and my expectations from working in a new company. The HR manager was friendly and professional, which created a comfortable atmosphere for communication.
The second stage consisted of a technical interview with two developers. They offered several live coding tasks related to creating a RESTful API, processing data, and using multithreading in Node.js. The tasks were interesting and challenging for me, but I was able to successfully solve most of them due to my experience and preparation.
The third stage consisted of interacting with future colleagues and discussing the projects the team is working on. This allowed me to get an idea of the company culture and the team dynamics.
Overall, I was impressed by the professionalism of the team and the approach to the interview. Although some of the questions were challenging, they helped me better understand what competencies are key for this position. I left the interview feeling positive and ready to join Netflix.
The Netflix interview loop is intense and lives up to its reputation. The recruiters are great, but the technical bar is absolute top tier. After a technical phone screen, the virtual onsite consisted of two deep system design rounds, a practical coding round, and very heavy behavioral rounds focused purely on their Culture Memo. They do not care about how many LeetCode hards you have memorized. They care about how you reason through scale, failure, and ambiguity.
Recruiter screen high level discussion.
Tech phone screen live programming exercise.
Virtual onsite, 3 tech rounds two culture/behavioral.
For mine it was like an out-of-body experience, except when I turned to look it wasn't a body at all; it was a plane. Watched it take off, seemed like maybe the pilot hit the throttle a little hard trying to reach cruising altitude and then.. dunno, maybe he dropped his cigarette under the seat or there was a bee in the cockpit or something because next thing you know he's flailing around while I watch the plane tumbling, helplessly aghast as a wing shears off from the stresses he's inducing. No survivors.
But seriously, good interview process. Very helpful recruiter team that will spend time detailing the process and expectations. Exercises are very realistic applied engineering stuff, not brain teasers or obscure algorithms or stuff you haven't done since college. Interview process may be different across the org so YMMV. I interviewed with the Content and Business Products side of the house (i.e., tools for studio, production, not streaming to end users) and the coding, sys design, and data modeling rounds all reflected that.
My advice to you: study the OSS software they publish, know your stuff and *stay calm*.
