If you want to get an IT job in North America, there’s no avoiding algorithms and data structures. For a lot of international students, Python is the best language to start with. Its syntax is clean and simple, letting you focus on solving problems instead of getting tangled in complicated code.
When you’re just starting out, it’s smart to learn the basics first — things like arrays, linked lists, hash tables, stacks, and queues. They seem straightforward, but in real problems, there are always little details to watch out for. Common interview tasks like reversing a linked list, finding the middle element with fast and slow pointers, or checking matching brackets with a stack all fall under this. Writing these with Python usually makes the code easier to read and debug.
Once you’re comfortable, you’ll want to dive into tougher topics like binary trees, graphs, heaps, sorting, recursion, and dynamic programming. Dynamic programming can be tricky, but it’s a must-have skill for mid to senior-level interviews. When you practice, don’t just try to get the answer — think about what the problem really means and how different solutions compare in speed and efficiency.
One big plus of using Python on platforms like LeetCode or Hackerrank is that you can write less code to solve tricky problems. But remember, Python isn’t the fastest language when it comes to running speed. After you finish, it’s good to look at how efficient your code is and see if you can make it better. Sometimes, just changing your data structure, like swapping a list for a set, can speed things up a lot.
For international students, getting good at algorithms and data structures isn’t just about passing interviews. It also helps you think more clearly and systematically, which is useful whether you’re building backend services, analyzing data, or working in AI and machine learning. So it’s best to start early while you’re still in school, and give yourself plenty of time to practice. Mastering Python along with solid algorithm skills is a key step to breaking into the North American IT job market.
