I wish I had seen this before interviewing with SpaceX. They don't do too much Leetcode coding challenge but rather they emphasize on system design, the first phone interview is right on system design.
Just came here directly after getting asked system design in the first interview... The recruiter didn't even mention it in the preparation email, and this is an intern position, so I was kind of shocked.
Translate an ambiguous problem statement into CONCRETE one. Articulate design decisions THROUGHOUT the discussions. Know the pros and cons of different approaches. Get comfortable with white drawing tools. Give mocks. Hyper Aware of time management. Think out loud. Focus on broader tradeoffs rather than low level designs.
They have a paid course "System Design Interview" - which is a series of 30 very in-depth articles on general topics and most asked interview questions (like "design youtube", "design url shortener", etc.) Each of these articles follows strict framework of presenting your interview answer. Some of these 30 articles are free btw, so you can check them out.
Just directly study the distributed systems course, it's a free/open online class and will teach you everything from a practical aspect, not these gimmicky jargons.
I have been around the block and find those interviews have gone overboard in recent years. I have never seen any architects being asked software development questions.
Will be great if you can do a separate video for staff level system design interviews. There are still many resources or there such that anyone with few years of experience can do a decent job at system design. So it's important to differentiate.
I don't think you would need a dedicated video for staff level interview if you are skilled enough and I think it is up for the interviewer to assess that. In my opinion, this video caters to direction on how to do it generally.

Can I ask you for advice, I got a final stage interview as a "Security and Compliance analyst" role but it is non technical and I don't know if it's worth it.

Who typically has to do these kinds of interviews? Is it just devops people, or software engineers too? I am a senior level full-stack (front-end leaning) software engineer, and I have never done a system design interview in this depth. Usually i'll just be asked about a previous project I have led or created by myself, and we'll do a deep dive.

00:36 🏗 A system design interview assesses your ability to translate ambiguous problems into technical requirements, design architecture, and defend your decisions. 01:30 📈 Your performance in a system design interview can impact whether you land a senior engineer position or a more junior role. 03:03 🖌 Practice by designing real-world applications like Instagram or Uber, sketching out core components and interactions. 04:13 🔄 Study common design patterns, know their pros and cons, and be prepared to justify your choices during interviews. 05:49 🗣 During interviews, ask targetedquestions to understand requirements, manage your time wisely, think out loud, and explain your design decisions clearly.
I mean, if half of all the interviewees can perfectly design an instagram system, what are the big asses at FB with shiny titles sitting there for? If they can't, what's the point of the whole story telling?
How do people handle these questions when you're attempting to narrow down the scope of the question, yet the interviewer really isn't giving you much. i.e. build new gym Clarifying questions, who is it for? What kind of gym? Where is the gym located? What constraints do we have? Interviewer doesn't give any good direction. I then make assumptions and then have to explain why, but during the interview this feels wrong
Hmm, I guess from a software perspective, you'd ask more software/application related questions. Are you building a website for the gym, or dedicated application, or both? If application, desktop, mobile, or both? What will the the primary use of the gym service? To let new clients register, to let employees manage administrative tasks, or both? Does it handle payment transactions? If so, how frequently, what discounts are offered, etc? For content, does it provide features for trainers and what type? Setting schedules, designing training programs? Do clients track their workouts and days attending? Do we send notifications/emails to clients when their next payments are near due? Things like that. At the end, you may get the following summary: * A desktop and mobile gym application for users and employees. * Users register in the app and make their weekly/monthly payments. * Each user has a unique QR code to scan for entering the gym. * Users get notifications when their subscription plans are about to expire, if they have not renewed it already. * Employees can view new employees, which plans they are on, as well as when their plans expire. * Employees can revoke or permit access for different clients using the application. * Etc Don't worry too much. In a 1 hour interview, it's usually fine to spend 3-8 minutes asking questions and clarifying or detailing features.
I'm not a programmer just a wannabe at this point but I think this a real-world scenario that you would face and they're trying to see how you would handle it. Most people don't know what they want until you show them a mockup, then they have all sorts of suggestions lol so they are testing to see if your thought process is recyclable /reusable and how you think forward and don't code yourself into a corner. Clients usually don't give you much to go on in the beginning so it's up to you to come up with a solution that is flexible and won't require "scorching the earth" to pivot in a new direction.
In hindsight, I think I only addressed a high level frontend side of it. Mostly because the question was "make a gym". Now if we were going into system level, you'd have to consider load balancers, databases, object stores, queues, caches, etc etc.
This is absolute perfection. I recently read a similar book, and it was absolute perfection. "Mastering AWS: A Software Engineers Guide" by Nathan Vale
My salary was reduced coz I couldn’t find the issues with a system design I’m a program manager not even an engineering resource to have such expectations , I feel it’s done to cover up inherent engineering team flaws , it’s all about whom to blame when the design fails.

@@deonrobinson4293 Your comment is meaningless. The majority of "senior engineer" work occurs on existing/established designs. You don't need to design youtube before you can do 99.99% of software engineering..
