Here’s a scenario that probably sounds familiar: It’s Monday morning and your dev team is knee-deep in a React e-commerce build for Client A. Wednesday rolls around and they’re suddenly debugging some ancient PHP monstrosity for Client B. By Friday afternoon, there’s an “urgent” mobile app feature that absolutely must ship before the weekend… gotta meet those expectations!

This is typical agency life. And if you’ve been in this game long enough, you know that context-switching isn’t just common, it’s literally how we survive (and thrive).

I’ve spent over a decade as a CTO hiring hundreds of developers, and here’s what I’ve learned: technical skills alone don’t predict who’s going to thrive in the beautiful chaos. The developers who actually succeed are the ones who can mentally pivot between projects, technologies, and completely different problems without having a breakdown.

The question is: how do you spot these 🦄 unicorns 🦄 before you hire them?

Why Hiring Can Get This Wrong

Most developers are trained to go deep. They want to get into flow state, work on a single codebase for weeks, and really build expertise over time. That works great if you’re building the next great SaaS product with a stable roadmap and predictable sprints.

But agencies? They live in a completely different universe. They’ve got multiple clients running different tech stacks. Project timelines that seemingly change hourly. Constant interruptions and shifting priorities. And the never-ending need to ramp up quickly on never before seen codebases.

The traditional hiring playbook (you know, leetcode problems and whiteboard algorithms) completely misses this reality. You end up hiring brilliant developers who can solve complex algorithmic challenges but absolutely crumble when they have to juggle three different client projects in a single day.

I learned this the traditional way by making mistakes. Early in my CTO days, I hired some incredibly smart people who just couldn’t handle the constant context switching. They’d get frustrated, overwhelmed, and eventually burn out. Not because they weren’t good developers, but because they weren’t the right fit for the beautiful agency chaos.

What Context-Switching Really Means in Practice

Let me be specific about what we’re actually talking about here, because “context-switching” sounds like business jargon, but it’s very real:

  • Technical Context-Switching: You’re moving between JavaScript and Python. Frontend styling and backend APIs. Shiny new React builds and legacy WordPress sites that haven’t been touched since 2015 (but still need to work perfectly).
  • Business Context-Switching: One client is a healthcare startup that needs HIPAA compliance. The next is a retail company that just wants their checkout flow to stop breaking. Each has different priorities, different budgets, and completely different definitions of “urgent” and “done.”
  • Mental Context-Switching: This is the hardest part. Remembering where you left off on each project. Quickly getting back into problem-solving mode on codebases you haven’t touched in days, weeks or months. Staying productive despite constant interruptions. And somehow maintaining attention to detail across multiple streams of work.

The Red Flags I Watch For

After hiring hundreds of developers, I’ve learned to spot the ones who struggle with context-switching pretty quickly:

  • The Perfectionist: These developers want to refactor every piece of legacy code they touch. Great for long-term product development, terrible when you need a quick fix for tomorrow’s client demo. I once had a developer spend several days “improving” a simple bug fix because the existing code “wasn’t following best practices.”
  • The Deep-Dive Specialist: They get genuinely frustrated when pulled away from complex problems. You’ll hear them say things like “I need at least 4 hours of uninterrupted time to be productive.” In agency life, you’re lucky to get 45 minutes without an interruption (I aim for 20 min!)
  • The Framework Purist: They refuse to work with “outdated” technologies. When they see jQuery or PHP, they immediately start advocating for a complete rewrite.
  • The Feature Creep Developer: They can’t resist adding “just one more small improvement” that turns a 2-hour task into a 2-day project. Their heart is in the right place, but they don’t understand that sometimes “good enough to ship” can be 10x better than “perfect but late.”

These aren’t bad developers. They’re just not necessarily equipped for the world of agency.

What Actually Works in Agency Life

The developers who thrive in high-context-switching environments share some specific traits:

  • They’re comfortable with ambiguity. They ask good clarifying questions but don’t get paralyzed by incomplete requirements. They’re fine making reasonable assumptions and iterating as they learn more.
  • They’re pragmatic problem-solvers. They choose the solution that works within real constraints rather than the textbook-perfect solution. They genuinely understand that “good enough to ship” often beats “perfect but late.”
  • They’re technology agnostic. They see programming languages and frameworks as tools, not personal identities. They might prefer React, but they won’t have an existential crisis when asked to fix something in Angular.
  • They communicate really well. They document their work, leave clear comments, and can quickly explain their thought process to someone else who might need to take over tomorrow.
  • They actually seem to thrive on variety. This is the big one. Instead of getting stressed by changing priorities or unexpected urgency, they seem energized by it.

Practical Interview Questions

Forget the whiteboard coding. Here are the questions I’ve learned to ask:

  • “Tell me about a time you had to quickly learn a new technology for a project. Walk me through your approach.”
    • I’m listening for: Do they have a structured way of learning? Are they comfortable with documentation? Can they find and leverage existing solutions instead of reinventing everything?
  • “Describe a situation where you had to switch between multiple urgent tasks. How did you manage your time and mental energy?”
    • I want to hear: Specific strategies they use. Evidence that they understand their own working style. Proof that they’ve actually done this successfully before.
  • “How would you approach joining a project mid-stream with completely unfamiliar code?”
    • I’m looking for: A systematic approach to understanding existing code. Questions about documentation and team communication. Realistic expectations about timelines.
  • “Give me an example of when you had to choose between code quality and deadline pressure.”
    • This reveals: Do they understand business context? Can they articulate technical debt vs delivery trade-offs? Do they have examples of making pragmatic decisions?

The answers tell me everything I need to know about whether they can handle the agency realities.

Setting Your Team Up for Success

Once you’ve hired these context-switching superstars, you need to set them up for success:

  • Make handoffs easy. Good documentation isn’t optional when people are constantly switching between projects. It’s literally survival.
  • Set realistic expectations. Context-switching has overhead. A developer juggling three projects won’t be 100% productive on any single one, and that’s okay.
  • Protect some focus time. Even the best context-switchers need some uninterrupted time for complex problems. Build this into your scheduling.
  • Share knowledge regularly. Brief updates between team members so everyone has some context on all projects, even if they’re not actively working on them. This makes emergency handoffs much less painful.

The Bottom Line

In agency life, the ability to context-switch effectively is often more valuable than being a 10x developer in one narrow area. The developers who thrive are the ones who can mentally pivot quickly, work pragmatically under pressure, and maintain quality across multiple concurrent projects.

Stop hiring for the developer you wish you could afford to have work on one project for six months. Start hiring for the developer who can make three clients happy using three different technologies in one week.

That’s honestly the difference between surviving and thriving in this business.
