First, I'd understand the application requirements. Assuming it's a typical web application, I'd start simple: single load balancer routing to multiple app servers behind it, a managed database like RDS, and CDN for static content. This handles the first phase. As we scale, I'd move the database to a multi-AZ setup with read replicas for read-heavy queries. I'd implement caching with Redis to reduce database load. I'd set up auto-scaling groups so the app tier scales automatically. I'd use a content distribution network for static assets. For observability, I'd implement centralized logging and monitoring from day one so I can see what's breaking before it becomes a problem. I'd also plan for database growth—eventually we might need sharding if a single database can't handle the write volume, but I'd cross that bridge when we get there. I'd design with cost in mind—not over-provisioning upfront, but building the ability to scale incrementally. Also critical: I'd architect so we can do deployments without downtime using rolling updates and health checks.

While you'll be asked questions surrounding technical requirements and experience unique to specific roles in an interview, the collaborative nature of IT means recruiters and hiring managers place a heavy emphasis on the ability to work across business functions and collaborate with a team. Here are several sought-after skills to be aware of as you prepare to answer IT interview questions, so that you can emphasize them in your responses: Effective Listening “I'm always looking for candidates to demonstrate they're good listeners, as understanding others and translating that into action is a key component of success in IT,” says Rene Daughtry, a solution services manager for Cisco's PMO Americas division. Understanding how coworkers use information and manage data is an important part of any IT role. Show that you're attentive and will understand your colleague's needs by being a good listener in your interview. And when you think of stories to tell in your interview, try to remember ones where you asked questions, sought examples, and had clients to show you how they planned to use your work product. Problem-Solving “I want to see how candidates approach problems and situations, particularly when they may not have all the information,” Brooks says. “Good problem solvers know to look to others who may have faced similar challenges and seek them out.” You can share these skills in your interview by talking about examples of when you looked to others for help in approaching a problem you weren't familiar with. If you're an early career candidate and don't have examples from past IT roles, maybe it was the first time you drove a car with a stick shift or when you had to use unfamiliar software to complete a class project. When the interview question calls for it, you want to emphasize the approach you take in getting more information and how you act upon it. Hunger for Learning With technologies and business needs evolving so rapidly, eagerness to learn is a quality highly prized by IT hiring managers. “The interest and desire in learning—about the business, the market we are in, the challenges we face, and what technologies best support success—is critical for me,” Daughtry says.

I use historical data and growth trends to forecast capacity. I pull metrics from our monitoring system—CPU, memory, disk, network—over time, usually the past 12 months, and identify trends. If we're growing 10% month-over-month, I project forward six months and determine when we'll hit 80% capacity, which is my signal to act. I've also set up auto-scaling in AWS so non-critical services scale automatically during traffic spikes, which handles short-term bumps without permanently increasing infrastructure. For databases, capacity planning is more manual—databases can't just add disk space invisibly. I work with the DBA to monitor growth and provision additional storage before we hit limits. I also use this data to push back on over-provisioning; if we provision for a worst-case that never happens, we're wasting budget.

I once deleted a security group rule thinking it wasn't being used, which broke database connectivity for a staging environment. I realized it immediately when I started seeing connection errors in logs. I could have quietly recreated the rule, but instead I immediately notified the team that this was my error and the ETA for fix. I restored the rule (took seconds), verified connectivity, then spent time tracing what actually used that security group to understand why it was there in the first place. Turned out the documentation was outdated, so I updated it. I also set up a read-only check on security group changes so another engineer reviews deletions before they happen. It was embarrassing, but treating it transparently rather than quietly fixing it built trust with the team.

The development team wanted a new staging environment with high specs to test load scenarios, and the security team wanted us to implement a new vulnerability scanning process that required infrastructure changes. Both were urgent, both had merit, and both would consume my time. Instead of just picking one, I sat down with both teams. Development's staging need was actually more flexible than they initially said—they could share resources with another team's staging. Security's scanning was genuinely important for compliance.
