When applying for tech jobs in North America, technical interviews are a standard part of most companies’ candidate screening process. Many international students have practiced plenty of problems, but still get nervous during interviews or aren’t sure what interviewers are really looking for. Knowing the process and preparing in advance can help you showcase your skills effectively.
Most companies’ technical interviews focus on a few types of questions: algorithms, system design, and basic technical knowledge (such as Java, Python, databases, and networking). The first round is usually an online coding test on platforms like CoderPad, Karat, or via Zoom screen sharing, where you solve one or two medium-level algorithm problems. This stage tests your fundamentals—questions aren’t too hard but require clear thinking and clean code.
Don’t rush to write code right away. When you get the problem, first restate it in your own words to confirm understanding, then explain your general approach. For example, “I plan to use a hash map to optimize time complexity, by scanning the array once…” This helps interviewers follow your logic and point out issues early. Some interviewers care more about your communication and thought process than just coding skills.
If you face a problem you don’t know, don’t panic. Start by suggesting a brute force solution, then gradually improve it. Even if you don’t finish, it’s better than staying silent or giving up. Interviewers value your problem-solving process over a perfect answer.
Later stages may include system design questions, even for recent grads. Be ready to discuss basics like designing a notification system or a URL shortener. Talk about how to break down modules, choose databases, and scale for large users. Details aren’t critical, but a solid overall approach is expected.
Technical interviews also test foundational knowledge, such as “the difference between threads and processes” or “the four properties of database transactions.” These take time to build up and can’t be crammed last minute. Regularly review key concepts, especially those listed on your resume, since you can be asked anytime.
Lastly, don’t underestimate communication. Technical interviews are not just about solving problems but also about showing how you collaborate and think. Speak logically and stay calm—this leaves a better impression even if your answers aren’t perfect.
For international students, technical interviews can be tough, but also a chance to stand out. With solid preparation and the right mindset, every round becomes a step closer to landing that ideal offer.
