Two Worlds, Two Playbooks
Big tech and scrappy startups may seem like opposite ends of the job market, but they share one thing in common: both are fiercely competing for top talent. If you’re a strong candidate, you might find yourself interviewing with a FAANG giant one week and a ten-person startup the next. On paper, that sounds exciting. In reality, it can be confusing.
The trap many candidates fall into is assuming one style of prep works everywhere. They think endless Leetcode grinding will cover all bases—or, on the flip side, that being “culture fit” is enough to carry them through. The truth is, the FAANG interview and the startup interview run on two completely different playbooks. What works in one setting may actually backfire in the other.
This article unpacks those differences. We’ll look at how FAANG’s structured, multi-round process contrasts with startups’ faster, more fluid conversations. You’ll see why FAANG wants proof you can operate at scale, while startups want reassurance you can roll up your sleeves on day one. More importantly, you’ll learn how to adapt your preparation so you don’t walk into either room underprepared—or over-rehearsed. By the end, you’ll have a roadmap for preparing smart, not just hard, no matter which world you’re aiming for.
The FAANG Interview — Scale, Structure, and Depth
When people talk about “the toughest interviews,” FAANG companies are usually at the top of the list—and not without reason. These organizations (Meta, Amazon, Apple, Netflix, and Google) have built recruitment machines that are designed for scale, consistency, and accuracy. The process isn’t just about finding the smartest engineer or the most creative marketer; it’s about filtering for people who can thrive in a fast-moving, principle-driven environment.
The Multi-Round Journey
A typical FAANG hiring journey stretches across several rounds, each one serving a very specific purpose. It usually begins with a recruiter screen, followed by technical or role-specific assessments, and then multiple rounds of in-depth interviews with team members and managers. The hallmark of this process is transparency: recruiters often share the upcoming steps and may even outline what skills each stage is meant to evaluate. This structure reduces randomness—every candidate is measured against the same rubric, not individual interviewer whims.
Technical Intensity
On the technical side, preparation is almost a prerequisite. Platforms like Leetcode have become a training ground for software engineers, since FAANG interviews are well known for algorithm challenges, data structure problems, and system design scenarios. The focus is rarely on solving the “trick” question itself; it’s about demonstrating scalability in your thinking, clarity in your trade-offs, and adherence to best practices. For example, a system design question isn’t only about building an app that “works,” but about how it will handle millions of concurrent users without collapsing.
Behavioral Depth
Equally critical—but often underestimated—are the behavioral interviews. Amazon is the most famous here, with its Leadership Principles serving as the backbone of every interview question. But other FAANG firms also use their own cultural values as a yardstick. Expect questions like: “Tell me about a time you disagreed with your team but had to move forward anyway.” These aren’t filler questions; they test whether your approach to collaboration, ownership, and problem-solving aligns with the company’s DNA.
The Common Pitfall
One of the most frequent mistakes candidates make is focusing exclusively on technical prep while neglecting behavioral preparation. Too many strong coders fail not because they can’t solve problems, but because they struggle to articulate teamwork stories, leadership moments, or how they embody principles like “Customer Obsession” or “Bias for Action.”
Smart Preparation with AI
This is where tools can shift the balance. For instance, with Sensei AI, you can upload your résumé and practice structured behavioral questions that mirror FAANG’s principle-driven approach. Instead of vague rehearsals, you get targeted prompts—helping you frame experiences in a way that’s both authentic and aligned with the leadership qualities these companies prize.

The Startup Interview — Agility and Versatility
If the FAANG interview feels like a meticulously organized marathon, the startup interview is closer to a fast-paced sprint. Startups move quickly, and so do their hiring processes. What they lack in formality, they make up for in intensity and unpredictability. You might find yourself speaking directly with the founder, the CTO, or even the small team you’d be working with day-to-day. In many cases, the entire process could wrap up in a week—or even a single day.
Shorter, Looser, but Higher Stakes
Because startups often can’t afford lengthy, multi-round assessments, they compress interviews into fewer stages. A phone chat might be followed by a technical screen, then a final conversation with decision-makers. Don’t mistake “shorter” for “easier.” Each conversation carries more weight, because the margin for error is thin: one poor impression can cost you the offer, while one strong performance can secure it almost immediately.
Practical Technical Focus
Unlike FAANG’s algorithm-heavy approach, startups usually want to know: Can you build, fix, and deliver right now? Technical assessments are grounded in practicality—debugging an API, sketching a quick architecture for a new feature, or explaining how you’d handle scaling with limited resources. They’re often looking for full-stack thinking—someone who can cross boundaries, connect dots, and adapt when the roadmap changes tomorrow. It’s less about perfect optimization, more about resourcefulness.
Conversational Behavioral Checks
Behavioral interviews at startups often feel less scripted and more conversational. A founder might casually ask: “How do you handle stress when everything breaks at once?” or “Why do you want to work at a company our size instead of a big name?” These aren’t just small talk—they probe for cultural fit, resilience, and passion. At a 20-person company, one hire can reshape the entire dynamic, so authenticity and alignment matter as much as technical skill.
The Pitfall of Over-Preparation
One of the most common mistakes candidates make is walking into a startup interview with a rigid, textbook-style approach. Rehearsed STAR stories, overly polished technical answers, and “perfect” corporate-sounding phrases can backfire. Startups value agility—if you sound too rehearsed, they might doubt whether you can handle the chaos and ambiguity of a real startup environment.
Training for Flexibility
The key is to prepare with flexibility in mind. This is where Sensei AI can help: its AI Playground can generate both quantitative prompts and cultural-fit scenarios — you can use it to create mixed practice sets and manually alternate between technical problems and conversational answers, training the exact switch startups test for.

Key Differences at a Glance
After exploring both worlds, it helps to step back and look at the contrasts side by side. FAANG and startups both demand excellence, but they measure it in very different ways.
Aspect | FAANG (Big Tech) | Startups |
Hiring Process | Multi-stage, standardized, often weeks or months long. | Short, fast-moving, sometimes just a few days, often involving founders directly. |
Technical Focus | Heavy emphasis on algorithms, scalability, and system design best practices. | Practical skills, problem-solving, and ability to wear multiple hats (full-stack mindset). |
Behavioral Focus | Structured questions tied to leadership principles or corporate values. | Conversational style, probing passion, resilience, and cultural alignment. |
Evaluation Lens | Looks for candidates who can thrive at scale and drive long-term impact. | Looks for candidates who can create immediate value with limited resources. |
Common Pitfall | Over-focusing on coding prep while neglecting behavioral interviews. | Sounding too rigid or “corporate,” failing to show flexibility and adaptability. |
The Big Picture
Here’s the bottom line: large companies test whether you can amplify value inside a massive, structured system. They want to know you can slot into well-defined roles and still drive excellence at scale.
Startups, by contrast, are laser-focused on immediate contribution. They don’t have the luxury of long onboarding or trial-and-error—they need people who can jump in, troubleshoot, and make progress fast.
Why This Matters for Preparation
This means you can’t recycle the same interview prep for both. A Leetcode grind and polished STAR answers might impress at FAANG but fall flat in a startup chat. Likewise, walking into a FAANG panel with only scrappy, project-based examples may leave gaps when the interview turns to system design depth.
The smartest candidates build two playbooks: one geared toward structured, scalable excellence (FAANG), and another for pragmatic, culture-driven adaptability (startups). Knowing when to pull from which toolkit can make the difference between a near-miss and an offer.
How to Stay Ready for Both Worlds
If you’re serious about landing offers in both FAANG and startup environments, the smartest move is to prepare on two tracks at once. It’s not about doubling the workload—it’s about building flexibility into your preparation so you can walk into any interview room with confidence.
Build a “Dual-Track” Prep Strategy
Think of FAANG prep as your technical gym. You’ll want to stay sharp on algorithms, system design, and scalable architectures. Platforms like Leetcode and mock system design sessions will keep your fundamentals ready for the rigor of big tech panels.
At the same time, carve out space for startup-style practice. This means crafting examples that show resourcefulness, initiative, and hands-on execution. If you’ve ever hacked together a prototype, led a side project, or juggled multiple roles, those stories are gold in a startup interview. The key is to balance depth (for FAANG) with breadth (for startups).
Showcase Projects and Side Work
One of the best ways to bridge the two tracks is to keep a living portfolio of projects or side hustles. For FAANG, frame these projects in terms of scale and impact—how many users you served, how you improved performance, how you optimized for growth. For startups, shift the lens: talk about how quickly you iterated, how you solved problems with limited tools, or how you built momentum without a big safety net.
Adjust How You Tell the Story
It’s not just the examples you pick—it’s how you narrate them. At a big company, emphasize how your work plugged into larger systems, created efficiencies, or scaled solutions. At a startup, spotlight your scrappiness: the late nights debugging, the moments you wore three hats, the way you kept momentum going when resources were thin. Same story, two different spins.
Smart Tools for Smarter Prep
This is where practice tools can make preparation smoother. With Sensei AI’s AI Playground or Editor, candidates can create two tailored versions of their resume—one geared toward FAANG’s structured rigor, the other toward startup versatility. You can also simulate both interview contexts, practicing responses that highlight scale on one track and adaptability on the other. That way, when an opportunity lands in your inbox, you’re not scrambling—you’re already prepared to show the version of yourself that fits.
The Takeaway
The real advantage isn’t choosing FAANG over startups, or vice versa. It’s being ready for both—and knowing how to pivot your narrative depending on who’s sitting across the table. Build that adaptability into your prep now, and you’ll never feel out of place, no matter the stage or setting.

Prep Smarter, Play Both Games
Whether you’re chasing the prestige of FAANG or the adrenaline of a startup, the message is clear: both paths demand excellence—but they measure it differently. FAANG interviews reward structured thinking, scalability, and cultural alignment with leadership principles. Startups reward adaptability, initiative, and the ability to thrive in uncertainty.
The best candidates don’t bet everything on one approach. Instead, they learn to adjust their stories, highlight different aspects of their skills, and bring the right energy to the right table. That doesn’t mean reinventing yourself; it means building range.
So as you prepare, resist the urge to “pick a lane.” Instead, master both playbooks. Keep your technical fundamentals sharp for FAANG. Collect scrappy, hands-on examples for startups. Then practice shifting between the two.
Do that, and you won’t just be ready for one type of interview—you’ll be ready for any door that opens. After all, the future of work isn’t about choosing big or small. It’s about being the kind of professional who can thrive in both.
FAQ
Should I join a startup or big tech?
It depends on your goals. Big tech offers structured training, stability, and a brand name that opens doors later. Startups give you breadth — you’ll likely wear multiple hats and see the direct impact of your work. If you value career “safety nets,” big tech wins. If you want steep learning curves and ownership early, startups might be the better bet.
What is the biggest killer of startups?
Lack of product–market fit. Most startups don’t fail because the founders aren’t smart or the team isn’t working hard. They fail because the product doesn’t solve a real enough problem or doesn’t find customers fast enough. Poor cash flow management and founder conflict are also common, but product–market fit is the number one killer.
Who pays more, startups or MNC?
In the short term, multinational corporations (MNCs) like FAANG usually pay more in base salary and benefits. Startups often can’t match that, but they may offer equity, which could pay off big — or be worth nothing. Think of MNCs as higher guaranteed compensation and startups as higher risk–reward.
Why do people leave FAANG?
Some leave for faster growth and bigger responsibility than they can get in a large, layered company. Others feel constrained by bureaucracy or want to build something of their own. Burnout can also be a factor, given the intensity and pace. Many people leave not because FAANG is “bad,” but because they’re ready for a different style of challenge.
